Tell you the truth this is not the right time to start another free vps service. Because sponsors are getting harder and harder to find. Smaller Server providers loosing their business to big companies these days. It's quite hard to complete with prices these big companies offer. Anyway I agree it's better to have a TLD and its more important to find several sponsor because starting your service. You need to approach hosting providers and see if they are willing sponsor. But first you need to figure what you can offer them in return.

Yea, there is a lot of concurrence between small companies and big companies, but I think just to try it first.
