3rd-party-product for people-listing with country/zip

[symptome]

In my forum I want to list people of a certain profession.
They shall have the ability to enter their data in a given profile and this is show to all visitors.
Visitors shall select with country and zip-range to see profiles.

How did you solve this? Is there a 3rd-party-product to vb, I could use?
And is there a possibility to get paid for every entry?

Thanks!
