You reckon you could build and run this as a service for $0.05 a user per month? Whilst perhaps scraping profit? Care to share some of your own products, I'm keen to see how sustainable your business models are.

Why are you forcing the look from the provider's perspective? OP mentioned an alternative that is cheaper (free), so it's expensive from user's perspective.

I don’t sell product like this. I do use WordPress for free on a shared host averaging about $1/site.

My problem is not making money by selling this type of service. My problem is finding a good tool.

It’s interesting that people think users care about provider profit models. What’s an acceptable profit? I certainly don’t know and don’t really care.

Sustainability and viability are not linked.

Of course they are. There's no viable project or service that is not sustainable.
