All of these post's I have found both interesting and true. This is one of the hardest times when anyone can go and get the materials to do what they believe they can do.
The most important thing for me to be concerned with, as someone stated earlier, is to have the proper testing equipment and cover my rear with my guarantee's in regard to the performance of cabling that someone else has installed.
Owning a small business is tough and I am sure that they (small business owner) wants to cut costs. But I give several examples and references in regards to the quality of my work, as well as, the cost benefits of doing it right the first time. More often than not the customer sees my point of view.

Part of sales is to earn trust, and part of installer is to keep it and build it.
