Actually this would qualify under the semi-pro or maybe actually the guy without a license.

If you are not doing you own electrical WHENEVER POSSIBLE you are missing out on a huge area of profit. It's REALLY simple...anyone can grasp the concepts - look at how stupid sooooo many electricians are!

Forget selling central vaccuum as an upsell!

Screw all those lame popcorn machines!

The profit margin a lot of times on electrical is way above 1000%

For example, you COULD (not recommended) sell all your A/V equipment to the customer at cost and still come out ahead if there is an equal amount of electrical work to be done. Charge normal electrician rates for electrical and discount the "flashy" A/V - give them a TV at cost, they love that!

Otherwise I agree for the MOST PART of your post.
