Congratulation! Share your story in your blog or something. I will be curious and follow your progress. Couple years ago, I almost started like you but then gave up. I am in IT and wanted to get away from it. I started doing research and made a lot progress. The idea was to start a kiosk business at the local mall and then expand. Start up cost was low but it was still too risky. In the process I convinced a retired pilot to start a similar thing and he became very successful but I bailed out :-). My biggest challenge was getting some honest and stable people to work for me. I didn't want to quit my job and wife was and still is busy with kids. The second challenge was getting stuff (and the right/good/real stuff) imported from China. Lost some hard earned money but of course learned some good tricks. There are tons good ideas for kiosk business. At some point in the future, I will probably look into this again. With all the limitations I have, I thought of doing something on the side within IT. I think it's better. So I started a mobile app development business. The first app is built and submitted to Apple yesterday. The same app I am also making it for Android market and will submit soon. I learned the process so now the plan is to outsource everything and I will just manage the high level stuff. I sharing everything thru my blog
