if you are considering it as a business model - I would suggest you contact Mercedes Ashley and pay her to share her experience, knowledge and ideas.
Mercedes has been offering 1 to 1 skype "conversations" already for a long time and is definitely an industry veteran. The price is $100 for 15min.

not that I'm her pimp... for some unexplainable reason I just really respect her - she's gone through tons of sh*! and is as a very good business women (rather that b***).
Good luck,
Helmuts
