Wow, there are so many you can begin.

The best bet is to look at three things to make the decision:

1. What are your skills, the things you are good at?
2. What do you enjoy; what are you passionate about?
3. What is the market demanding right now ?

My preference is usually for a service business, as the startup costs are lower and the margins higher. As you mention, tourism is a great entry-style business. So, too, are computer consulting, real estate and so on.

Hope this helps.  Brad Sugars
