Need your ideas on best social networking script for my situation

Hey everyone,

I need to create a nanny site similar to http://www.gonannies.com

It doesn’t need to be very in depth…

The requirements are:

  • Search by zipcode on home page.
  • Nannies can create a profile for free/ upload pics, interests, qualifications etc…
  • When people search for nannies they can see pictures but can’t access contact or location information. They will need to register and purchase a plan before they can contact nanny.

What is the best social networking script available for this type of job?

Im open to paid and open source.

I might be also be interesed in outsoucing this to a developer, but right now i’m just looking at ideas before I think about hiring someone.

Thanks
