I don't think people pay money for this type of thing. They do for CMSs or hosted solutions of any type, but no so much for starter kits.
I think it will be a long road to get traction selling this, but if you want, you could promote and give away the starter kit for free, then sell add-ons that tackle difficult tasks. You could make money this way.
Again, I think there are easier ways to make money, but my first steps would be to promote the heck out of this free starter kit. Then solicit suggestions from your user base for additional features or custom work. You could do this with a forum. Pick the feature requests that you think would be the most difficult for your users to do themselves and that also provide value to their business (bonus points for value easily identified with dollar signs) and then make them as add-ons to sell.
My motivation for this was seeing that people regularly pay freelancers on oDesk/elance hundreds of dollars for this kind of thing. Or perhaps they're paying way less than that, but they're waiting weeks just to get that first buggy 1.0 version deployed.
So I think there is real value here for someone who wants to get their basic webapp 1.0 version out as quickly as possible, and not have to pull their hair out over stupid things like signups, or Facebook integration.
I am in fact sitting on some Adsense ads for this, but first I wanted to get some basic feedback on whether I'm totally off-base or not with the idea. Thanks!
Thing is, it's not like a non-technical person is going to download this and say "Awesome, no need to pay a developer to build this now - all I have to do is implement a few SQL tables and forms and I'm done" - they'll still need the developer, just now they can get more done for their small v1.0 budget.
