You might want to try your hand at iPhone games. There's currently a lot of room in the industry for new players. It has low barriers to entry, yet people are seeing a huge return on investments, and you can get projects out the door in a smaller time frame than most games take to develop and market. To me, it seems like the perfect space for a new business with little capital and lots of skill. I'd even say its perfectly suited to you. You can learn a new language and practically make yourself golden when it comes to being employed if your venture doesn't work out, because there's huge demand for iPhone programmers.
