C#.net application required for Inventory mgmt

Hi, I need an application (preferably C#.net) which would use an MS Access database. I need to be able to do the following. 1) Add/Modify/Delete products (with some validation like numeric (3 char max), Aphanumeric (10 char max) etc.) 2) Generate 3-4 reports (very simple - based on simple calculation) 3) Loginid/password for access 4) 3-4 users should be able to use it simultaneously as we have many products to be added/modified daily Note: We do NOT want a purchase/Sales module. Its just ADD/modify data in the database and generation of few reports. So the work is pretty simple. And I am looking to have it in 3-4 days time. Thanks
