An opportunity?

My husband thinks he's come up with a way for us to take over a small business and I would run it. I'm undecided about it. I've thought about it and while it's not a bad opportunity, I'm not sure I want to be tied to something either. On the one hand ... it would be cool to run it and be responsible for the success of the business, BUT on the other hand ... it would be a little while before we started making any money (hopefully we'd make money!) and we would be the only ones working there. My husband has talked to the current owner and now I just need to decide if I want to commit.
