PhP Programmer required for an Auction site.

Dear Programmers, Greetings from the Auction site, We need original and professional website which will be in 95% similar to Penny Auction sites like: [login to view URL], [login to view URL], [login to view URL], [login to view URL], madbid.com. The script must be tested and 100 PERCENT bug free. A full working demo is needed for us to test before we can make the payments. Also, a full support of 90 days is needed upon purchasing the script. Upon completion of the projection, and testing by us, it is agreed that we own the script. You must also install the application on our server and make it so it is relatively secure from any kind of hacking. We need all auction platform that includes everything from the bidding process, to registration, buying bids, autobidder.

A very important point is the software will includes some mathematical calculation methods which are not familiar in classic Penny Auctions. If you have a previous built Auction software, it'll help speeds up the process but other than that, the original version is not much valuable to us. Code must be customizable, changeable and adjustable in the future. We need to get SOURCE CODE to be able to change ourself everything what we would like in future with no restrictions. The site must have an easy to use administrative control panel. It is very important how it looks, it is also important to function correctly because users only see final product off course. Actually we prefer to be able to easy change more of everything on site as much as we can. The site should function normaly using any of popular browsers (Internet Explorer, Mozilla, Google Chrome, Safari and more) The design should be simple but good looking and easy to navigate for users. The point is more on functionality and easy for eye using purpose than fancy design with a bunch of graphics floating aroung. So seeking a clean, professional design that will be easy to navigate. So we want to avoid the repeating look of the other sites out there and to give our customers the best that we can offer with our unique service. We prefer experts who have experience in building or customizing Penny Auction scripts and Penny Auction websites or similar. Your experience in this area will make the communicate easier and faster.
