Designing and previewing engraving for magento shop

We're looking to work with someone to develop a proof-of-concept idea for a flash application that allows customers to design engraving for a product on our ecommerce shop. For example - lets say our customer wants to engrave a flower vase. The user will be presented with the option to engrave up to 4 lines (limited characters per line) and optionally a graphic from a pre-defined library. The user will be able to type in their 4 lines of engraving, change the font, and optionally. The user will be able to save the design, come back and edit later, then purchase whenever ready. Any bids submitted must prove they have a sufficient level of proficiency with Flash/Actionscript. At this time I'm not interested in working with someone who hasn't worked on a project that is similar (for example a t-shirt design app). Must be able to provide some sort of working demo of previous work done that I can evaluate for relevancy. * Specify 4 lines of engraving for a product * Change the font of each line * Show the price of engraving and and add it to shopping cart
