You can be in business for yourself, if you start your own wooden floor installation service business. It's pretty easy, if you can measure, and cut pretty accurately, and don't mind spending lots of time on your hands and knees. You will do good in a flooring installation business of your own, if you can do those things. Most newer homes these days, have lots of new wood flooring throughout the house.
Lots of homeowners, and property investors, are also pulling up their old Laminate Hardwood Flooring Guys and replacing them with more desirable wooden floors that customers demand. You can find various flooring materials from, discount laminated flooring pieces, to nice real hardwood flooring. If you can measure and cut pieces of wood pretty accurately, and you like putting big jig saw puzzles together, than you should start your own flooring installation business.
You can make up a flier, and contact painters, and other home improvement companies in your area, and let them know you install flooring. Tell them that you will give them a commission, for any jobs they send your way. Sometimes a homeowner has the floors done last, while remodeling, and painters usually work there, before the flooring guys put the floors in. So if the painter can put in a good word for you, or hand their customer one of your fliers, that's one of the best ways to network, and get more customers for yourself.
Make sure you have a nice sign on your vehicle, so others can call you, when they see your auto parked somewhere, while you're inside working. You can also put ads in local newspapers to get customers, or pass out fliers house to house until you do several hundred of them, and then you will have some business pretty quickly.
