I cna create the applictaion in about 3 days. I admit that graphics are not by strong point. what I can do is create a fully functional application meeting all your requests. The application will be designed in PHP. I can make a simple interface for it, which you can embed in your website. If you want complex graphics for it, or if you want the application to be standalone and not included in your website then I think I won't be able to do it. Yet, I hope we will colaborate.
