WordPress membership provider and extending profile data

I’m building a site where I need to provide additional fields for user profile data. I will have roughly 30 additional fields. I have seen that there are ways to add additional fields to a profile but I am also considering installing a membership provider plugin. I’m looking for some recommendations on what my best route would be. The general site layout is that users register, they post photos of themselves. Users are groups into two category types, individuals and companies. Users can search on any of these custom fields to find other users. There are tiered user levels (ie. bronze, silver, gold). Users have to pay subscriptions for access to some content and features. The site will use galleries heavily and then users will have some interaction with other users to where they can pick their friends, etc.
