Customised Craigs List Clone

I need a customised clone of Craigs List. The website is actually going to be an adult content website but I want to implement a Craigs List format and concept. Budget is small, so please be fair and considerate in your bid. This bid price will include the script with the installation, customising and website design. I want to start this project ASAP if the price is right and will also like to see a demo and portfolio. Thanks
