J.S.
I, too, do this myself. I use hot water and liquid fabric softener to remove the wallpaper, let the wall dry for a day, and then paint it. However, I only remove the wallpaper if it's starting to come up, otherwise, I just paint over it with 2-3 coats.
I would go down to your local paint store and ask bout contractors, since most of the time the people at the local stores know them and may be able to recommend them. Good luck.
