I love Quickbooks. Although I worked in the Finance department for quite some time, I didn't realize how difficult doing the books of a business really was. Fortunately I am a quick learner, had an awesome accountant and was able to use my husbands business as

I wouldn't recommend offering it as a service right off the bat. First get familiar with your software and take some tutorials. You seem to have the foundation layed with already having some accounting classes under your belt and wanting to take some refresher courses is great.
