Web development

I need you to design and build it. I would like to create a website like freelancer but for another target market. The way it would work is as follows: 1. In the main landing page, the user is asked to input relevant search query or project data. 2. Price quotation request is sent out to all subscribing industry members in the directory. 3. Members receive email notification inviting them to post/amend quotations freelancer style. 4. User awards winning bidder based on price or rating. 5. Funds are deposited by user and put in escrow. 6. User or service provider confirms delivery of quoted product our service. 7. Funds are released. The system should be clean, lean and clutter free. In the initial stages there'll be no private messaging on the platform except between customer and service provider only after job or ticket has been awarded or ordered. I'm also expecting a safe and secure payment gateway, ideally paypal. Any job awarded should be commenced upon immediately and without delay and completed on time as per bid. I'm expecting initial results up on the server within 24 hours to showcase that work has commenced. Reasonable accommodation should be given to provide ongoing support and amendments. I'm thinking wordpress as CMS to ensure uninterrupted security updates, but phone GAP built for mobile responsiveness. The directory should be crawl free as access to information is contingent on individual user request for a quote which will be pushed to all members of the directory/list. The target market is one industry to start with. Just think freelancer but without 90% of the technological features like awards, milestone payments, user profiles, etc The only thing I'll maintain is the feedback system to determine service delivery and as a price determinant, recommendation tool when two or more service providers offer up the same price. Let me know if this sounds interesting.
