That would be most of the replies here on that very same note. Its one thing to host a dinky site (and that is not meant to be bad) but compared to hosting say your local banks website, another company that "has to be" up all the time - things like that need more than just a garage or a basement.

We all start somewhere, so its possible you could start up, but at some point you are going to need more room and more resources than a small room in a home could handle.
