This is pretty much the exact path I took. It becomes really interesting when it finally dawns on you that there's very little difference between building and selling a 3 to 4 figure / mo SaaS and offering a value-oriented consulting retainer to a few clients. (See http://draft.nu/revise/)

While retainers aren't exactly turnkey (they'll generally require human effort per account per month), the same positioning, marketing, and pricing rules you'll encounter selling software apply.
