The SimplePortal community is pretty small, so you can expect it might be a while before someone comes along and is interested in carrying your idea out for you. Unfortunately, bumping your topic is not likely to help you very much.
If you are interested in learning, you might try posting on one of the SMF coding boards, or even on a php forum. You are bound to learn a lot that way.
Good Luck to you; I hope you can figure out the customizations your forum community needs.
