Good alternative for "Pro-Sites"

Does anyone know of a good plugin like Pro Sites (https://premium.wpmudev.org/project/pro-sites/). I want to be able to sell websites created on my wordpress network, and it looks like Pro-sites is the only plugin I can find that will do this (without having to build my own, of course). There are a few things that I don’t like about Pro-sites and I wanted to know if there were any good alternatives? Thanks!
