Gotham, any reason you don't or cannot fix it yourself? learning how to use a mig is easy, they can be had for cheap, sheet metal is cheap and besides that...all you need is a hammer and an angle grinder.
Start by exposing good metal with a flapper or a fiber disc, next draw a pattern to cut and chop it using a metal cutting blade. trim cardboard to the size of your cut, transfer it to sheet metal. if it needs to be curved...that is where the hammer comes in, once you trim/form the sheet to the hole ...line it up and tack it in place, continue stitching it 1 inch at a time to minimise distortion, work on one side then switch to the other. finish cleaning the welds with a flap wheel to perfection..apply seam sealer where needed.
Even a novice welder (that cares) will do a better job then any commercial body shop (that don't). I'll bet you can get it all done for an total expense of about $500...including buying the mig (ok, using shielded wire, no gas) grinder, assorted wheels and sheet metal...unless you score a killer deal on a used mig setup.
It's really easy once you get the hang of it....it doesn't take long to get to "getting the hang of it".
