Having once cutting my wrist open (vein, not artery thankfully and missed the tendons my 2mm) with a 12" angle grinder, I know only too well that they need to be treated with respect. But also a firm hand and not fanny about with them.
Despite that, I'm quite poor when it comes to PSE and mainly only use a face shield when using a twist knot brush on the angle grinder. Yes, I'v had one of those leap at me only to shred my Tee-shirt near my neck!
Back on topic, IF I was in a position to offer welding services on cars (which I keep declining) then my ESTIMATE would be starting from around £500 for the job you picture. They ALWAYS look better than they actually are

I'm the same- navy surplus welding overalls, goggles, ear defenders, leather gauntlets, safety boots... don't give a **** what I look like. Won't use a wire cup brush on the grinder though after I snapped the side handle off and dislocated a finger, that wasn't that nice. Ouch........ I'm not a fan of cup wheels they tend to grab a lot but those evil b'stard zip wheels send little tiny spikes that I normally end up pulling out of my arms and chest. I have to say that not much comes close for surface rust removal so I put up with it.

Having had welding done in the past by 'professionals' I taught myself to weld, and although the results aren't always that pretty they are at least strong! What was it they said on one of the american car shows? You don't have to be a good welder if you're a good grinder!
I too have had fights with angle grinders, mainly trying to use a small 'un when I should have been using a 9", and managed to hit myself in the mouth when it kicked back. I've got a healthy respect for them but it won't stop me using them.
Of course I may just be completely stupid!

I still use them but a bit worried about using in all the tight spots. I was planning on cutting the easy to get to bits out tomorrow and have a look for any further rust. If i am to Cut out say the outer sill will i need to close it up asap? Car will be kept in a garage

With the prices given for welding a price given by a known company for welding in the Subframe mounting kit for my car sounds reasonable. I would weld it but upside down welding really is not my forte!

Car will be kept in a garage Nope - can be left open for a long as you need Unless your garage roof leaks like a sieve like mine does!!! Edited to add - not much progress on the car front as I'm pretending to be a roofer (trying to fix the leaks)

Already have a wire liner. From having a go with it before there is always a issue with the wire feed

I assume the trim pot is for the wire speed? It does already have wire speed adjustment or are you saying thats not good?

If you mean the wire feed trim on the front of the case - that's fine (although I changed mine for a 10 turn pot and counter (but then I did that because I changed the wire feed supply to a stand alone with a separate transformer) and then I put a pulse width modulator control system on to increase the motor feed power - it's frankly a bloody slippery slope that unless you enjoy fiddling with an SIP welder as opposed to welding up a car I'd recommend that you stick to just the basic stuff that makes a big difference but doesn't end up creating compromises So the wire feed control I refer to is the 1000 Ohm trim pot on the circuit board - this is very coarse to set up - the 100 ohm trim pot is a much finer control makes the "calibration" of the start point easier - some machines already had that some didn't it's worth a look to check.....

Already have a wire liner. From having a go with it before there is always a issue with the wire feed Snap. Mine never used to feed the wire through correctly until I did two things: -Got a very good quality wire liner going to the gun -Got hold of a fresh and large reel of welding wire. That transformed the wire feeding ability and the inability of me not being able to weld, or so I thought. I also have a large bottle of gas on mine, but if you have the bottles I'd use them first .

Alot was hidden behind sideskirts etc Ahhh sideskirts - great invention for hiding rust caused by dirt build up trapped between them and the sill - Dirt captures the salt and keeps it close to the sills and the rust fairies weave their magic to make metal disappear...... Case in Point - Early Monzas had no side skirts and always seem to have perfect sills - later Monza GSE's have side skirts - normally have no sills left by the time the skirts are removed or fall off due to no fixings left to hold them on......

Water got captured in the rears and escaped when jacked up. Never jacked up it must have got stuck. I have never driven the car in the winter, and even very rarely in the rain. Just never always put in the garage

What was it they said on one of the american car shows? You don't have to be a good welder if you're a good grinder! NO!! I'm sorry, but just NO! If a weld isn't 'pretty', then it's not going to be as strong as it should be either. Id you have to grind it back cos it looks like snot, then you should grind it ALL out and start again. You should only need to lightly flap wheel it back to blend in the panel joints. I'm sorry to be negative, but one thing that really p1sses me off is people saying a weld doesn't have to be pretty to be strong. Well sorry but, yes it does. True, you can get half decent looking welds with no penetration, but you can't get strong pigeon sh1t either!

Started cutting out some rust yesterday but at 30c was too hot to wear all the safety gear so stopped and stripped the interior. Found some more rust which is a bit curse word seems People were right saying its worse than you first find. Inner sills have also started to rot. The rust on the inner arches as worried me how to go about cutting such awkward shape out and how to bend a new piece to shape.
