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.
