[CentOS] Fiel uploading framework

I need to setup something for a group of CAD guys to provide a web interface for
clients/customers to send files to them. I was hoping to have an interface where the
customer would be given a logon and it would email a link to the employee upon his
successful upload. This would require an internal facing site to provision a slot to give
to a customer.

Anyone know of a project like this so I wouldn't have to manage any aspect of it?

Thanks!
