I own some very well-followed social accounts. How can I make this a business?

I run a number of Twitter, Tumblr, Pinterest, and Instagram accounts which hundreds of thousands of followers in large niches (fashion, technology, film, music, student, etc) and through these can grow these and other accounts at a rate of 10,000 per day if I work on this full time (currently am a consultant with a background in content sites hence social/traffic driving background. Not necessarily looking to do a startup (i.e. a lifestyle or e-commerce business would work for now) but open to all ideas. As content is very hard to make money from (sadly) I'm thinking to sell a product through the site, i.e. clothes, possibly with a local focus. Am I thinking too small? I have a lot of experience in community management so can grow lots of accounts of engaged people and have sent millions of clicks to sites, but would like to use this for myself rather than clients so I have a fanatical startup focus. Any ideas really appreciated, thank you!
