That's ok, but that's a services business. That means committing time. It's difficult to build a fly-wheel that way. I guess you could outsource on oDesk or similar.
I do not think anyone should sell products without understanding the service part of doing business.
if you buy something, people expect someone to be responsible for the product. This mean you got to spend time on providing service, or it get defined by most people as a cash grab.
