I think free hosting plan will be good way to attract some members who will actually buy premium packages after testing for few months and what i don't like in all the common free hosting plan is they have lots of limitation on the type of sites we can run as well as they also don't have support to latest scripting language.

I like your plan to have quality free hosting and also paid hosting beneath it and i think this could get some success if you accept bitcoin (obviously) and have plans comparatively cheaper than other hosting where bitcoin is accepted. I have gone through several bitcoin accepted hosting sites and found their price is way higher for same thing which we can get from other hosting where bitcoin is not supported.
