business advertising site / script required.

I require a complete design and installation of a website or script which is aimed for local businesses within my target area. I have a few ideas for design but im sure a gumtree / craigslist style site would be suffice. I would like a complete price to create upload and test the site with a minimum of 1 months support if required. Site hosting is ready so job needs completed a.s.a.p. Further work could develop. Please bid accordingly.
