A business that I have always been fascinated in is the candy bar wrapping business. If you have ever gotten one of those neat candy bars for a baby announcement, party invitation or even a business card, then you probably know the basic idea of this business.
Basically, with this business you design wrappers that go around candy bars and other similar items. People buy these from you so they can announce a baby's arrival, an invite to a party, a memorable business advertisement and many other creative ideas. Once that wrapper is designed, you can either sell the wrappers with instructions on wrapping the candy bars or you can do the wrapping as well. Some candy wrapper businesses offer both options and so they aren't missing out on those customers who might want to save a little money by purchasing their own candy.
This is a good business to do if you have small children around as it won't require you to do a lot of phone work. You can do most business via website/email, design the wrappers on the computer and wrap the candy while watching your kids. The hardest part will be keeping them out of your business candy!
