I'm not saying it is impossible. I am suggesting that it is hard and the hard part is talking to people about something that they might not want.
PageRocket is a really nice piece of work and could be the basis for a profitable business I think. But that profitable business probably means going out and selling to one customer at a time...there are a lot of small businesses in the world for which PageRocket could be a very very good solution.
Currently, I see a possible business that is closer to the design agency end of the spectrum than the Wordpress end. Design agencies ship and don't really launch.
37 Signals is that sort of model. It was a design agency that eventually built a product, Basecamp. StackOverflow is sort of similar...Fog Creek Software was both a consultancy and built FogBugz. Slack was a game company before it hit on a product.
I want to reiterate that the process for PageRocket is well designed and the aesthetic results tasteful. I suppose one way of putting it is that the quality of what I see suggests that the team is capable of building something businesses might pay 'real' money for and I hate the idea that the bar would be set at a place where doing so becomes unlikely. So in the end, I guess I am encouraging you to aim higher or at least at higher fees.
