Alpha User Points / Jomsocial Modification

Good day all! :) I need a modification done to my site that allows users to invest Alpha User Points in Jomsocial Group Admins (called Projects Admins on my site) through the Group Description (Project Description) layout. The points are basically redeemable as money so it'll be used to fund projects that other users make. I basically want to add an input box to the group description layout on Jomsocial that allows you to enter an amount and when you hit the "Invest" button, it automatically credits the group owner with the points. I'm not too concerned with where it appears on the page - I can tinker with that myself - but I can't come up with the code for an input box that directly gives to a user from that page. My site is bittyshare dot com if you want to have a look. Looking for a long-term thing here too :) Happy Bidding!
