I am looking for web developers with experience building a 3-tier web site with auction/sweepstakes type functionality. A key component of the final product is that the website be quite scalable and configurable. In general, the site is a fairly straightforward endeavor, with a few exceptions: Winners are chosen via winning ticket, which is selected at random by a computer program. Tickets are mainly purchased but can be awarded by various other means; tickets serve as the only means of winning an item in the drawing. Sellers can donate all or part of their winnings to various causes.
A database component with multiple tables (i.e., customer, product, payment, feature management, etc.) will support the backend. The database must also support the process for uploading and cataloging product images by the seller will and general account management activities. E-mail confirmation for various stages in the process along with multiple email communication options must be supported. The website should support Pay Pal and other payment gateway options.
