Construction Project Lead Generator

Looking to create a website that is a networking/ advertising tool, and a bidding site for contractors. This site will be free for project owners to post projects, that contractors will in turn be bidding on. There should be 2 quadrants to this site, first would be project owners area. This area would allow a project owner to sign up and create his/her own project profile. This project profile would then go to a database with all other project profiles which are held for an assigned period of time. Each project would then be distributed accordingly to qualified/ registered contractors falling under that particular project category. Projects will be broken down into the following categories; Cat. 1/ Project title Cat. 2/ Project title, project owner info, project address Second quadrant (Business) would be the contractors area. This area would allow contractors to sign up and create their own company profile. This company profile would go to a database of all other registered contractors. This company profile would be accessible to all project owners/ new visitors and other contractors. All contractors on the site have 3 options when registering with the site. 1/ Free Membership - Access to view all projects (cat. 1) - Access to view contractor directory 2/ Pay per Lead Membership - Access to view all projects (cat. 1) - Access to view (1 chosen) project (cat. 2) after payment has been made to site. (payments will vary based on scale of project) - Access to view contractor directory 3/ Semi Annual/ Annual Membership - Access to view all projects (cat.1) - Access to view all projects (cat.2) - Access to view contractor directory This site should be entirely interconnected and should always be promoting annual membership on each project lead (cat. 1) and every page on the site. That is the principal of the business plan "TO GET MEMBERSHIPS". There is a Canadian site I have been looking at [login to view URL] I would like it to operate in almost exactly the same manner. I need this site built in the 7 days following approval and am willing to pay up to $500 USD for site construction and $500 USD for timely completion. I will also require all web building software program info so that updates can be done by my associates either in my country or abroad. All hosting and purchase of URL is taken care of.
