You may want to wait until after the next "Extreme Horesepower" / AutoSalon or Motor Show and have a look at who is doing what to the cars. Some of the bigger shops are more of your supermarket brand painter (they do the job to an OK standard) but for 10G I would be looking for an real artist.
Also look at which cars win the best paint category, some of the Bling you see at the show looks good but wont win because the attention to detail isnt there (allignment of panels, orange peel, straightness, clean panels front and back etc) you will notice these things on your own car bun wont always pick them on someone elses at the show.
