I have the rights to sell movies from companies like sony, 20th cent. fox ect. My rights are for downloads only, not the boxed.

My problem I need help with is that the movies are very large files the smallest ones are arounf 500mb, so with my host I do not have the space so I use another server for the files, and I need the customer to purchase from my store and the download to start right away or get the download link by email. Can any one give any suggestions on this topic.

Any help would be great. Thank you

Eric
