As a professional social media marketer/consultant for a few major US companies, I'm glad to see this finally pop up. But are any of your solutions long term? That's a huge plus as a seller yourself. While your service is only feasible for smaller business/accounts. I'd maybe set up a package where you provide them with CRM and management software after 3 months or so, and basically all the know-how to do it themselves. But you retain a consultant status, and get paid monthly just to answer the occasional questions they have. A lot of small companies don't have that complex of social media needs, they just need a sense of vision (since most are clueless with social media), and a bit of teaching.
This may or may not have worked for me...
