Change user search script

I am in need of a freelancer to adjust the php search form on my site. This is a user search, were users for other users via Gender: Sexuality: Marital Status: Ethnic Origin: Country: Picture: Online/Offline: Sometimes this leaves an unsucessful search error as the search is to specific. I need the search to be narrowed down to something like [login to view URL] search form. please see: [login to view URL] this would take an expert within SQL and php, please apply if you fit the project. Thanks
