ASP.NET/Javascript/PHP Content Processing Application (VP.NET)

Need an application done. I prefer it to be done in ASP.net with VB.NET- in visual studio .net. 1. This will be loaded on our web server, so this will be a web application. 2. Simple login, username and password. 3. This application needs to be well designed and simple to use. 4. There will be several fields: Item number, Quantity, Price, Description and 3-4 other fields. 5. The application will have a refresh timer, or it can be refreshed manually. 6. The main process of the application will be: User will input item number, the application will go on eBay and it will pull quantity, price, and description. 7. There will be few more fields (no more than 5), which would be simple. 8. We will do color fields based on the changes. There will be few other minor customizations. For example if original price is $500, new price is $475, make it green, $525 make it red. This has to be in ASP.NET VB.NET Thats basically it, the appliation needs to look nice to a client. We do many applications, so we need someone experienced who can work on similar projects frequentyly.
