Advice for new Wp Based Business

I’ve registered and am planning on creating a paid for mutlisite network where startups can create their startup focused site within a few clicks from preconfigured site templates.

I know wpmudev provides a few great plugins like the one for creating subsites from site template, pro sites etc but looking for any additional tips or advice about the setup which anyone thinks could make the automation more fluid.

Additionally wondering if you guys have some thoughts on what a good fee could be. I’m planning on having very low cost monthly fee sites with subdomain and a few special plugins and then more advanced, custom domain and premium plugin/theme option with slightly higher fee.
