Finances. You need to be good at quick math and be able to make quick decisions. You have to be careful how much you pay for a book, and then keep careful track of the expenses involved in selling it. For instance, when you sell on a website, they’ll take a commission from the sale. In addition, some sites, like eBay, will charge you a listing fee for each book. If you request that your money be deposited via PayPal, then you’ll be charged a transaction fee per book. If you’re not careful, the fees will quickly negate your profits.
Location. The most successful bed and breakfasts are those that are convenient to airports, historic parts of town, or other tourist attractions. That’s because there are two types of guests who tend to frequent B&B’s: business travelers who are tired of sterile hotel rooms, and families looking for a unique experience. That’s not to say that you can’t develop a successful B&B if your home isn’t located in the perfect spot, but you might have to work harder to make it a success if it isn’t.
The key is to make the class sound unique and irresistible. Don’t just teach a cooking class; come up with specialty cooking classes. You might teach a class on how to make artesian breads, or cinnamon rolls that rival Cinnabon. The possibilities are endless, and if you consistently offer educational and fun classes, you’ll have people signing up over and over again.
