bla.st clone (sort of)

What I need: I need a basic clone of the site: [login to view URL] There are features on [login to view URL] that I am not interested in which should make the job much easier. They are listed at the bottom of this post. Please see my basic requirements below. The basic functions of the site should be the same: Cards are ordered by cost/day. Whoever pays the most per day has their card at the top of the front page and/or their chosen categories. The cards are then ordered from highest paying to lowest. Free cards are listed last. Customer must be able to choose how many days their card is online and how much they want to pay, from as little as 1c/day. Cards paying the same amount/day will be ordered by date added, with oldest cards first. The cards should be split over multiple pages if necessary. A customer can add money to their card at any time to improve their cost/day and position. Each card position will go up as higher paying cards expire, and go down as higher paying cards are added. The value of each card should be listed on the card detail page. If the customer is logged in, the card value will also appear under each card. This will be a brand-new site. Basic design should be included and the site should be created using current web standards including CSS for ease of design change. The site must allow the user to upload their "card" to be placed on the page it qualifies for. There should be two administrative options. One is to allow any and all cards as they come through. The other would be to allow the admin to view cards before they are placed online. For each advertisement, the following information should be made available via a hover screen like the original site. The price paid Number of days online Start and end date and time The number of people that have viewed your ad The number of people that have clicked on your ad The number of people that have viewed the details page for your ad The username of the user that uploaded the ad, and the other ads that user has uploaded The categories set for that ad All payments should be set-up to go through PayPal. We must have the ability to add pages to the site easily. We will add all auxilary pages such as the rules and regulations, about us, cost, advertising, etc. We only need a bid on the working portion of the site. The whole process other than approval or disapproval of each card should be automated and not REQUIRE human intervention. Here are the features I DO NOT NEED. Referral program Widgets to put on other sites Specific expertise: You should have experience with mysql databases, javascript, ajax, css, php and xhtml. Timeframe for delivery: I am not concerned with the time as much as I am with getting the project right. Please check out [login to view URL] VERY CAREFULLY and ask any questions you may have concerning what they have and what I have stated before making your best and final bid. Once work is complete all property and code will belong to me and none of the code can be made available to any other individual or entity. All copyrights to the program will be mine upon completion of coding and payment.
