My advice would be to get waaaaaaaay more specific about what you want to do, then find a business partner who knows the "ins and outs" of the industry and has a few contacts you folks can use to get your foot in the door.

Forget about going after enterprise level customers. Prove yourself to the small and medium sized businesses first.

Before you do any technical work, be able to answer the question: why on Earth should businesses use what you're offering? There's no right answer here, but your answer should be super convincing. I think the most common is that you are able to beat the competition on price (cuz you're going to have such low overhead, I presume), but you'll need more than that.

Hope that helps. As others have said, I believe I'd be more helpful if you were more specific on what you were trying to accomplish.

Best of luck!
