I have done a website for a client who now requires a page whereby his customers can upload files from their PC for him to receive. What is the best way to go about this?

using a server side script like php or asp.

There are some great extensions out there for creating Upload forms for your website... DMX Zone has a product that I use that is available in many server formats:
