Are there any free large file transfer services that offer embeddable dropboxes for websites?

Can you help me find a solution for this specific problem? I want to start a netlabel. I need for bands to be able to send me music. High-quality is not just preferable, it's necessary, so e-mail forwarding is not an option. It's not an option, because full albums at 320kb/s mp3 can reach sizes to the tune of 180mb, which exceeds the limits of single message size with services like Gmail and Yahoo! Mail. Sites like Megaupload and Rapishare are great . . . if you have a file that you want to send to someone you know, but that's not my situation. I need a way for people I don't know at any time, using my website, to send me huge files that I'll download to my personal computer at my convenience. So far, the best solution I've come across is a $10/mo. pro account with Mediafire; it allows one to embed a dropbox folder into a webpage. That's perfect, it's exactly what I want. I just don't want to pay $10/mo. Do you know of any free services that I could use as a solution to this problem?
