Well, coming from my perspective, this is very custom. Unless I'm really out of the "scene", I can't imagine this being a widely requested mod. That being said, I'm thinking you could actually probably do this on your own. You seem to have a bit of background knowledge. If you looked at the YaBBSE code you can seriously teach yourself almost every major feature and trick with PHP/MySQL... I did! I didn't know a thing about php before YaBBSE, and I now like to think I've become fairly competent.
Just list out what fields you'd need, add them in, look at how selects things like memberName's, id's, ect, call your fields, look at how YaBBSE displays information, and then try doing it. Even try just adding one row to the memberlist (like try adding an extra column to the memberlist with another piece of data in it using the YaBBSE code as an example) PHP is seriously user friendly because a lot of it talks in plain english. And I LOVE not having to ask someone to code something for me, wait for it, and feeling bad or like a bother for having them do it. (Even though they've always been more than happy to.)
If you don't think you can, though (but I know you can!

), you'd have to find someone with a touch of time on their hands to do it. This seems increasingly hard as SMF is steamrolling forward and school is on for quite a lot of people. However, if you someone to consult with on this or how you'd go about something, I could make myself available. Contact me on msn as

Hope this helps and good luck,
