Searcheable Membership

Hello and please forgive me if this has been discused before as I could not find the thread.

What I want to try:

I want to create a membership site (that may be chargeable) with say three different catagories.

I then want the public to come to the site (don’t we all) and search for members by keywords, if a match is found the matching members information; name, contact details, and brief description of services should be displayed in a friendly format say with a photo.

It sounds easy and I’m sure it is.

I had thought of using a membership plugin to control the registration page to membes who have paid a fee. I also though of using the same plugin to cintrol the public access so they too have to register but are not charged… how do I do the searching and displaying of results?

Thanks a very confused newbie.
