BuddyPress.org

I am creating a buddypress site. I am having a hard time figuring a few things out. I need to have two membership types: 1) user (buzzer) 2) biz-buzzers

The user is just a general user and can do just about everything except be in the biz-buzzers group and blog. The biz-buzzer is going to be a business that pays us (can pay online or offline) to be listed in the directory, be designated as a biz-buzzer, be able to blog, be a part of the private biz-buzzers group, and be able to use the biz-buzzer group forum.

My issue is what plug-in can I use to designate the 2 levels. I am giving 90 days free and a discounted membership to certain businesses and than to all other businesses it is one set price. How can I do this?

My other issue is how can I not show the biz-buzzers profile questions to just the general user? I only want the biz-buzzers group and options to fill out the biz-buzzers profile questions for biz-buzzers. I do want any user to be able to see biz-buzzers profiles. I just do not want everyone to fill out those questions.

Hope this makes sense. I really need to get this figured out because I want to launch the site by the end of the week. Thanks
