Setting up Multiple profiles?

I am Looking to see if anyone has an idea for me.

I am  looking for 2 things to set up my site for a specialty site.

I am looking for ideas on the site I am working on.

I need to create 2 separate join areas.

one link for the general public so that they can join to search/ and have their own profiles etc.

the other join link is for businesses that need to set up multiple profiles under their single account, for different items. without creating multiple log-ins  ex(one person with multiple personalities can create separate profiles using the same log in)

This is an example:

Site Homepage showing Misc information displayed, blogs, etc. with 2 buttons 1 for people, and 1 for businesses each  Then-links to 2 sides for each type of member with separate join and profile fields.

I need both to still be searchable/ matchable from both sides and function as one site. 

one of the reasons I need 2 sides is so that I can direct ads to each side.

I am fairly new to this program so please be as detailed as you can.

Thanks

Steve

Have a look at these modules:

Some of what you ask can be done with these modules.  Multiple profiles with a single login??? ... forget it.

Like HL says, multiple profiles with a single membership is a no no.... but you could considder this: http://www.boonex.com/m/Premium_Business_Listings

It will allow each business to list multiple locations, addresses, products, items, classes, services or whatever you set the categories and sub categries to. If you also have moddzzzz coupons and his reviews modules then each business listing you customers make can also include discount coupons and reviews of their products or services. These are all integrated modules.

Hope it helps.
