TECHNOLOGY TO USE Anything goes. This is a very straightforward concept with little functionality. However, this project obviously requires an understanding of multiple platforms and how to integrate them. With that in mind, I am open to solutions using any language, any database, and any web platform. Demonstrated functionality is the key to success on this project. No milestones. This is an all or nothing proposition. It works or it doesn't. Thanks for bidding!
