There are lots of options about starting some kind of group like that without needing money. It will be tough to find someone that will just sponsor you and give you money, if that's what you're looking for.
It also depends on what you mean by "channel" - are you planning on having something like podcasts every day or once a week to discuss religious things? Or, just a forum? There are plenty of websites that allow you to create your own website for free with forums and what not. It will give you a chance to start out and save some money and eventually have your own website.
There are also websites that allow you to post videos for free. One of these is called livestream, I believe.
I think Googling your questions would be your best bet, and use Google to find websites that support what you're trying to do to give you better advice.
