Scams abound in the travel industry -- particularly organizations that charge for information on how to break into the field. But operating a home-based travel agency can be an excellent business, says Tom Ogg, founder of HomeBasedTravelAgent. com. "Real home-based travel agents have experienced robust growth over the last decade, and there are probably 40,000-plus of them and growing." A growing (although small) number of people earn $100,000 or more a year, he says. "A solid business concept and plan focused on profitability will take you a long way to achieving your monetary goals." There's also the joy of helping others enjoy their leisure time.
