I would talk with Donna Reade from http://www.donnareade.com/
She is starting something like this. Tell her I sent you her way. She is fabulous at what she does. Let me know if you'd like me to make the introduction.
Depending on your goals and budget there are many courses on Lynda.com & Udemy.com.
If you have specific questions feel free to reach out to me.

As Allan noted below - would definitely recommend Donna Reade. She is the real deal.
