Sorry to hear about this. There are quite a number of folks with the knowledge (as evidenced by the previous responses) to help - and quite a few with the actual skills.

I know thetechknight has a number of videos on his YouTube channel in which he recaps and otherwise repairs Classic compact Mac logic boards. I obviously can't speak for him, but I'd bet his repair rates are fair and reasonable, if you feel you can't complete the repair yourself.
