Boonex Dolphin modification

Hello, I am looking to fire someone to make some changes to the boonex Dolphin script. I am creating a social networking site for contractors / service provider of all types, www.localcontractorsnetwork.com. I am needing to chance what I guess is the dating part of the signup / profiles, from "Im a Man seeking a woman" or vice versa within x miles of zip code. to "im a custome / client seeking a contractor, or mechanic" within x miles etc. I will need the ability to easily add different types of service providers. I currently only have the trial version as I am waiting to make sure this script will do everything I need. My goal for this site is to allow customers to find and meet service providers, be able to chat and message each other, avoiding the middle man taking their cut to sell leads to several people, this site will all be free for everyone, once popular there will be paid advertising etc to earn income to help with keeping the site running smoothly and pay for servers etc. thats pretty much what im looking for, i dont want it to be a dating site, but instead edit the dating section of it to join people with service providers in their area.
