Our company has a system similar to Mr. Sparky. I attended one of their seminars several years ago and found it to be insightful although pricy.
The only differance between what they do and what we do is that our employees are hourly and theirs are commisioned.
We have a invoice that lists all probable jobs with prices next to them.
It takes hard work to make it in this feild and even more to run a successful business with several employees. But the rewards are worth the headaches.
Anyone can do it if they have the ambition and financial backing.
I gained all of my knowledge by asking a friend who runs a very successful business plus a few hard knocks.
Their are two ESI companys in my area, one is strugeling the other is doing quite well which helps my company greatly.
