I must admit that I am not sure whether I understand what you plan to do, so let me try to rephrase it: you want people to fill out a profile to describe themselves, and then you use it to build them some kind of MySpace profile page, just hosted somewhere else? I could imagine that there are a few people willing to pay for that, if you host the page at a nice location (e.g. their own domain). Not sure whether this will help you learning about design though.
