PaintShop Pro allows you to remove backgrounds based on picking a color. They also have a Remove Background wand that will remove whatever you touch (converting those pixels to transparent). You can tweak the "tolerance" for the wand, such that it takes out pixels that are similar to the ones you are touching. This has worked pretty well for me in the past.

To automate it, you'd program a script in PSP that does what you want and then call it from your program. This might be a kludgy way to to do automatic replacement, but it would be the cheapest, fastest solution without having to write a bunch of C#/C++ imaging code or pay a commercial agency.

They being said, you pay for what you get.
