Sorry to be a bit blunt, but if you don't have many paying customers, and the only users so far are friends and family, and you suspect that some strong players will enter the field and crush you, what makes you think you have something that somebody would want to buy? If you don't have a compelling answer to that question, you should consider this one a training exercise, and move on to your next idea.

If you do have a good answer to the first question, then the next question is: who would find this product valuable? Who are the companies that would get some strategic value out of offering your product? Find them, and contact them.
