Hack to add questions to registration?

I'm looking for a hack (or someone who can build a hack) to add specific questions to the registration process, and the related members' data base and display page. Specifically:

Location (city, state/province)
Location (region, from a predefined list)
Member category (from a predefined list, ideally allowing members to identify themselves with more than one category, i.e. parent, professional, service provider)

Is there a general hack?

If not, is there someone who would be willing to build a hack (or hacks) for a non-profit (that translates to, "we can pay something, but not a lot").
