The problem with doing business with people who want to save money is ... they always want to save money. Everyone will want a free loss leader. You will be busy with that end of the business. Then, you will need to charge more your electrical work and they will go to your cheaper competition.
It would be better to do fewer surveys, for a reasonable price. Then, your customers will be paying customers and you won't need to recoup your loss leaders on your hourly rate.
The electrical survey is a good idea. I've done similar forms of it as power factor correction and thermal imaging. It's tough to sell because the results are hard to prove, especially if you don't find any problems.
Do you have thoughts about how to do a full survey?
