I wanted to try something too, so I decided that it should be a consumable product, reasonably priced and something most everybody enjoys. Affordable start up cost and a website maintained by someone else.
More importantly something I would enjoy! Thats how I picked the company I went with and so far I am very happy.
I've had to learn, I've had to get out of my comfort zone alittle at a time but I am doing it. You are right about the tax advantages I've worked at home for 5 years now and its a huge help.
My best advice have a passion for your product. Good luck!
