The only problem with this Matt is the quality of work as you may know.When you did a bit of paint before and repaired the arch at least you knew what was being cut out.I spent loads years ago on a Sapp colour change but also had sills/arches replaced plus I did all four doors bootlid and bonnet.It was a 2 year build and I used it for 3 months.
6 months down the line bubbling and lacquer peeling all over the place !.I sold it.
Nowadays I dont think I would be happy with any ones work unless its fucking mint !!.I suppose its worse because I have done prepping as a job.I should learn how to paint.
I just think as you would get more satisfaction doing it your self,I am sure as you have the capability/tools/space etc but if you cba then thats a different story lol.
