Selling Mograph

A follow up to my MacBook Pro question, I am curious how you guys who freelance sell your services and what types of business' you target?

I have a local agency client that has been keeping me pretty busy, but I would like to start selling to my own clients and building a business.

What is your pitch? How do you position your services? How do your clients typically share the content you create? Do you help on the back end getting their projects on Social Media, Web or Local TV? Any advice you could provide would be greatly appreciated!
