Promising Markets for a Startup Company

Konstantinos asks: "So far, I have worked as an IT manager in various projects, but I am fed up with someone else getting all the money out of my work. So, I want to do something on my own. Obviously, I don't want to take on the big guys as I will not have the resources or the time to be antagonistic, and I have to go after something totally different. I have made a small market research, but I don't want to risk my hard-earned money on something that is destined to flop. I had some ideas about niche markets that IT hasn't really touched, like agriculture. In your opinion, which are the most promising markets, for a one/two person startup company to try and tackle? I know that there is a risk in everything, and I understand that the IT business is under a global crisis, but I also know that there are some markets (esp. niche markets) that haven't had a significant hit in revenue due to the crisis. I would like to try and hit those markets. I am not afraid of work and I know that I can do the job and do it well, if only I find what it is! Thanks for any help."
