Not only because is very hard to a sale, you also become a kind-of-employee where your work for them, and have less freedom. And the requeriments change all the time. And the development can (and WILL) take years.

Plus, the corruption. Without "sales comissions" you can't even get the foot in. And you need to know people, and give them vines, go to a fancy restaurant, etc.

IF exist a enterprise somewhere that just do this: I need x, you can do it, let's do it, then I love to get in. I'm not afraid of "boring" CRUDs apps and that stuff.

But without the social connections and bribes,is a not start for me.
