There is not enough detail in your question to even give any specific advice to you. Like "what car should I buy.." Most importantly you haven't given any reason why you can't stay at the startup and continue to go to community college (cost, time from what you write don't appear to be a problem). Consequently (once again from the info you present) seems to be more of a downside to quitting then an upside to not finishing.
It's possible that going forward you will have to go beyond a BA so if you don't get that now where will you be? I'd stick it out and get the degree.
What do you do with the web hosting business? How many accounts do you have?
I don't think you can expect (with the limited info you are providing) though for anyone on HN to give you advice specific to your situation.
