I agree with all who said to do both.
If you want a software product to build and manage your own sites on both subscription and VOD and keep 100% of your revenue in-house take a look at
Elevated X
Good luck! As long as the content is hot you'll do well regardless of whether you decide just to sell it or build sites as well.
If you have questions about starting up sites I'm always happy to answer them.
