In lieu of real FTP, DropBox works really well.
I had never used it before, but we recently outsourced a pretty big After Effects job to an artist in Chicago, and that's what he uses. It seemed to work really well, even with really big files. Some were quite a bit bigger than the ones you are trying to send, and we had no problems.
