PHP/MySQL dynamic website

I need a website building to supply leads I am generating to businesses that want to buy them.

I require a database driven web application that allows users to specify the criteria of leads they require (product type, location, etc), pay money into the website (paypal?) and receive leads that match their requirement (which I have generated from a variety of origins).

I believe I need the following:

MySQL Database
User Control Panel
Site Administrator Control Panel / Content Management System
10 Web Pages
Blog Integration

My company is not yet formed but I have the infrastructure in place and buyers that want to purchase. I have a relatively good understanding of web technologies but do not possess the time or technical skills required for this project, hence the need to outsource.

I would like an operational, debugged and fully functional site within 60 days of authorizing work to begin. I will provide site hosting and domain.

I am working on a budget (aren't we all) but the quality of the end product is my main concern and in order to meet my budget I am open to advice and recommendations I can make to either my specification or method.

On successful completion of this project I would be very happy to offer more work to complete the satellite sites that support this website, I see this project very much as the start of a long term relationship and hope to build a successful business.

I have attached more detailed information and I look forward to hearing from interested developers as I aim to start as soon as possible.
