I appreciate the feedback here. I agree that there are tons of services that will help you increase with dodgy followers. However, that's a different market.
What is your market then?
What is your greater goal/long term vision?
Why would I want to hire your company for social-media management?
In my opinion, a successful social-media presence involves direct engagement with customers but most importantly business-specific knowledge.
For example, the Deutsche Bahn has a great social-media presence as they emulate a free and quick telephone service via Twitter. At any time, I can ask them what train I should take, which one is delayed, how I get from A to B, which tickets fit me best, etc. In your eyes, how is this possible using your platform?
