You can actually use your own computer as a server to set your site for free. All the directions are at this link: http://www.boonex.org/2007/08/07/those-interested-in-hosting-raydolphinorca-wamp5/

Don't make the mistake of wasting time on a costly server setting up your site. Once you have it set up you ought to be able to transfer the whole site to any host provider who can run Dolphin almost immediately, and there are a lot of cheap ones.

As far as bandwidth goes you will not use much see more of that for at least several months if not longer.

You can always move up to a larger plan once you begin to need it or even out right buy your own server...which a lot of people are starting to do. But don't buy anything you are not going to use right away thinking your site will have a huge membership with in a month. It is going to take you quite a bit longer...trust me on that.

Happyhosting.com can run Dolphin and is very cheap. $120 a year but you can not install Ray Media Server yourself because they do not even provide shell access. So you would have to have someone who works with them do it. I used this person who was excellent: http://www.expertzzz.com/expertsaccount/profile/praveenkv1988

Hope that helps.
