huge customization work

[zairafusco]

ok, i know probably this one is too big, i guess there is a lot of work involved, so i don't relly expect you to give me a full technical explanation about this issue but i hope you guys can just give me some hints so i can figure out the best way to start thinking about this issue:
i was requested to modify the personal profile page so each user can create (and manage, edit, delete..) up to 6-8 additional content boxes, each showing a small picture (much as an avatar size) and 3 data records, very short (like name, code, size) i think the best solution would be to build some more db tables linked to the userid (and of course a form for data and picture uploading) but i wonder if that's the best way or maybe it's easier to do something else, maybe working on some existing mods... i don't know... does anyone have some ideas about this issue?
i know guys it's something i should probably pay big money for, i'm just trying to put my best efforts in this work, and i learned so much here so.. any hint you can give me is most welcome!
