Research the product and local sources. Most likely whoever sells the lighting also offers seminars in installing and selling lighting. You can do it without the education, but you will do it better and more profitably with the know how. Check more than one source, the variety is staggering.
Buy a transformer and some different types of fixtures for your own home and play with them. The different fixtures, lamp wattages and beam spreads and installation methods. I have had excellent success with the Cast system and use their products and fixtures, also fixtures from other manufacturers adapted to the Cast system. http://www.cast-lighting.com/
Frog Lights sells a wide variety of specialized and unusual fixtures.
Great idea !! Lighting is very easy to do. You do not need a huge crew to do it and it is very profitable. As stated above you need to have a basic understanding of how to install and the effect that each light has.
To offer this , use coupon mailers or better yet most areas have magazines such as dinning out or some home improvement magazine. These should be tuned to higher income people upscale types.

The best thing to do is, learn how to do it right!!! You NEED to know how to calculate and USE voltage drop. When using line voltage, a loss of a couple of volts is nothing to worry about, but if you start out with 12 volts and you loose 2 volts, you don't have enough voltage to operate a lamp properly. I balance all of my lamps to 10.8 - 11.8 volts. If you can learn how to do this, use the very best equipment and stand behind your work (no matter what), you will be on your way.
