> Seriously. I can list tons of things that are reasonably profitable, but I, personally, don't want to do the hard work of customer support so I won't even start.

This in itself is a business idea. We need an Uber for Sales Support Staff that entrepreneurs can just rent by the hour.

I'd never use that because support is mostly dealing with company specific problems.

That will work at some point in the future, but it won't work right now, because B2B sales is still all about human relationships.
