Fail fast is good advice but not if you don't understand why you failed. Try to get information from your current users on why they aren't willing to pay for your service. Cycle on that and update your product to get a better understanding of what you need to produce as a product that people are willing to pay for. If you can learn from every effort then you can eventually get a winning product.

Also, understand that a product is not a business. A business is the supporting organization that produces the product. Get that going before you move on to something else.
