First of all, thanks a lot for your reply and I totally agree with you. See my first edit above:
> Yes, I know I should learn sales. I'm actually halfway through the first of two books about it. But to be honest, I am committed to another project that's taking most of my time and I'm basically trying to get this business to be as "autonomous" as possible.
I am currently trying to run this business, while working on a startup project and following Udacity's Tech Entrepreneur degree. It is very complicated for me to add sales to it now.
