Joseph,
Welcome! How many paintings do you have to copy, a lot or just a few. Do you own a professional camera or know a friend that has one? The photographer charging $460 for 2 paintings to be copied,seems high,even beyond high. Does he have a 4x5 scanning back maybe? Or a Medium Format Digital Back? Or just a good 35mm DSLR?
I personally like using a camera to copy artwork and used to do that professionally,with film and a 4x5 camera. Today, a good full frame sensored camera and the right lens, Macro,maybe 100mm would be fine, asl long as you follow the recipe. I can send you the "recipe" that I have and also suggest you look at my site here, for the "mechanics" of doing this yourself:

Most of the stuff is on page 2, but other good info on page one. You can do a search for me here and see if you can find my thread about copying artwork yourself or I can email you the info,
Good Luck,
Rich
