Learning to be a chimney sweep may mean nothing more than apprenticing with someone already in the business. By becoming a chimney expert, you can combine a chimney sweep business with a chimney inspection service--covering more than just whether or not the chimney needs cleaning but whether the chimney is in good working order or in need of repair.
There are many directions you can take this business. If you want to work during hours when no one else does, you can focus on office clients. You can focus on retail businesses and keep your customers clumped into one or two blocks. Restaurants are in great need of daily thorough cleaning and can be a great source of steady clients. Perhaps you would be more interested in house cleaning. Many times with cleaning services you don't have to spend lots of money on advertising or marketing because your customers will come by word of mouth.
Experience, training, or licensing may be needed
Dog walkers take pooches out for their daily constitutional one or more times a day, either individually or in small groups. In some cities across the United States, like New York, dog walking alone can be a booming business. But it's actually more common for dog walkers to offer additional services, including playing with and feeding pets, bringing in newspapers and mail, and turning lights on and off.
