Buddypress enhancement

hi, I am looking for someone to finish a project that is already started. The current programmer is too busy to finish it. What we have is a buddy press site that has a enhanced registration system. This is all working, the outstanding part is the paypal, Facebook and Twitter integration. We want a visitor to the site pay via Paypal to a member and leave a message that is posted to Facebook and twitter.
I can send detailed instructions to the right person. I also have a few smaller wordpress jobs that I need ongoing help with.
