393814 Clone for Craigslist

Hello, I have been researching the last couple days for a new venture I wanted to get help rolling out. I am looking to clone craigslist but also include a few more features. I am hoping to establish a strong business relationship and use the developer ongoing for updating the site and making changes when needed. I will need it also installed on my host server. Since I am a newbie I am looking for admin to be user friendly.
