asp.net, vb.net, File-management system

I am in need of a file management page for my website. The manager must work based off of authenticated users. Authenticated users will have the ability to create new folders in the directory, edit or delete folders. They will also have the ability to upload,delete,edit, view or download files. Non-authenticated users only have the ability to download or view files. I will handle which users are authenticated or not and this page will be on the backend so no need for any login. I would like the ability to restrict certain file types, but none at the moment. This page must be professional looking and drivin by css so that I can adapt the color scheme. I do require that the page is written in asp.net and any code behind be written in vb.net. I will except javascript as well. If you have any similar projects please show me to help make this process easier for both of us. My budget is between $30-50 usd and I need to have this project done within the next 2-3 days.
