[sick_of_web_dev]

I think the market is simply not there for such a tool. Your target audience are freelance web developers or rather a small subset of these. Add to that, that many of them are code monkeys that prefer to cook up something like this on their own and secondly the average freelance web developer doesn't really have terribly much money to spend to begin with.

I think you need a product that you can license to enterprise customers because they have plenty of money and often don't have a clue whether your product really is worth all the money or not.
