CUSTOM Auction Script

I am looking for someone who can create a custom auction script and install it on my web host. The features and options would be the same as a traditional auction service for the buyer and seller, such as Ebay. I can give you a full list upon request if needed. There are a few extras I would like to include. They are listed below: User friendly admin features so I can easily change options/text on the site. Multiple payment options (They choose what service to use other than PayPal) Each time someone buys something (or wins the auction), they get a credit after paying. They earn 3% of the amount that they purchase. The credit appears in their account. The option with what to do with the credit is to cash out using a payment service. The amount would have to be at least $10. (not including shipping or tax if any) The auction site is free to list (Except for banner advertising) but it would contain a final value fee of 10% of the sold auction amount. The site may require future upgrades with new features. The person who designs the script for me will be the person I will contact to do the job. Upon my request at the time of the upgrade, I will also pay you. If there is anyone who can help me create and install the script, it would be very much appreciated. Attached is the full list of Admin and User features I want installed. Subject to change. REMEMBER: This is more than just an auction script. I need it to be customized with different account options. The person who does the job must be able to do custom programming, not just selling me an auction script. The amount of time given is 1 month. I will need the design to be friendly and user friendly. So please take your time with the layout and make sure the scripts are clean so no problems occur in the future.
