Nadya,
look at our VFP-based products to build enterpise strength data-driven web applications -
http://www.arnicacorp.com. We also have a demo site with all products live. WebReport, FormServer, WebPortal - I think that this is what you need from the description of your project. You could use VFP code for all your programming, and don't have to use ASP programming.
