You want to be looking at paying less than £300 or doing it yourself if you ever want to make any money from the car chap. MIG welding mild steel is easy, it's the prep and finishing that takes the time, especially if you want it to look good.
It's very thin there (well the whole car is!) so you will need to put your welder on the lowest settings it will go, use 0.6 wire, tack all around the edges about every couple of inches or so then fill in the gaps between the tacks using short pulses rather than a continious weld as you will just blow through or warp the sh*t out of the panel. You need to weld like an inch or so, then move to another part of the patch, another patch or wait a bit. The idea here is to minimise distortion by limiting the heat that you put into the patch.
Making your repair patches will probably take the longest as they need to be pretty much perfect and butt up on ALL EDGES otherwise you will just blow through on such thin metal.
Or spend £20million and get a TIG lol.
