I think it will work better for ya. Certainly you've run across sites that show some small access for cheap, and more access for more money, and "requests over X calls / transaction / users, call for enterprise quote" kind of thing..

I assume these businesses are mainly looking for those high volume / high price clients and or people with that kind of money to buy them out completely.. all the while making a cheap plan for people to tinker with, build an MVP and maybe scale up.. and perhaps get enough mid range sales to prove they are worth something to others..

Of course that's not the game plan for every service out there. Anyhow good luck to ya, glad to see people working on ways to do things more privately one way or another.
