One has to do what is good for. If you say you are so product-focused but lost sight of sales, means that you better continue with your product development orientation. The business continuation would be with 3 options:
- find an independent sales guy with similar range of products. Sign a good product protective contract and leave him/her to do the sales job on a commission basis.
- get somebody who is close to you - from the family or friend, share the idea and help him/ her to start sales. As you say "feedback from customers and users has been wonderful", it would not be a problem to start sales activities with low profile and low budget.
or
- just find a good sales oriented company, with similar types of products. Share your idea / product and with good protective contract, become their product developer, as employee and let them take care for sales.
all the best
