Be afraid. Be very afraid.

That's the message many of us have about franchising. But Dr. John Hayes – a journalism professor turned franchising guru, after deciding in 1979 to write a book on the process – says while it's good to be fearful, we shouldn't let the risks block us from what could be the opportunity of a lifetime.

If you would like to own your own business, there are far more franchises available than you might imagine, extending well beyond Tim Hortons and the fast-food restaurants that we are familiar with.

Take Dental Fix: It services equipment in dentists' offices in your area, from mobile vans, one of many such servicing-on-wheels opportunities. Experimac sells and services Apple-brand products. As well, there's travel, executive coaching, laundries and a host of other non-food opportunities.

Instead of starting a business on your own, the franchisor gives you a boost, with a system that has worked successfully elsewhere.

Start your own pizza restaurant, he writes in his book, Take The Fear Out of Franchising, and you are on your own. You'll hit bumps along the road, even sinkholes, often self-made, which a franchisor would have helped you avoid.

That being said, he says it's legitimate – and wise – to be afraid. Franchise agreements are specific and long-term. They lock you into something that, if you haven't properly investigated, may be wrong for you – a bad business, or a great business that is just bad for you. "Franchising is not something you should take lightly," he says in an interview.

Based in Palm Beach, Fla., after seven years teaching at a private university in Kuwait, he sets out a number of tenets to be alert to:

"If you're a teacher and want to start a travel business, how will you know where to advertise and what to say? But the franchisor knows that, will give you the ad and tell you where to place it. They take the guesswork out and save you money, keeping you in business as a result," he says.

So, be afraid. Very afraid. But don't let that stop you from doing due diligence if you have always wanted to own your own business. It may be the right opportunity for you.
