I fundamentally don't disagree with your point. I agree you should charge what the market will bear. As a consultant I didn't get paid for my work product, I got paid to mitigate risk and provide a desired business outcome. Typically 10x my cost in revenue. In this case I don't perceive the value to be 10x the cost. I'd happily pay half of what they are quoting. I don't have to like the fact that installing a dryer outlet costs one quarter for the same labour and minor material cost differences. You need a circuit, 6 or 8 gauge wire, conduit, junctions, screws, an outlet box and an outlet. I'd happily source those materials and pay $200/hour for installation. Also $600+ for permits and inspection is just plain price gauging.You aren't paying for materials at Home Depot though, you're paying for them at your house, at the time they are needed. It's also worth mentioning that there are probably a ton of other smaller parts and pieces required that aren't itemized. I'm also not clear on why electricians are obligated to charge only a "modest fee" while providing a valuable service (which requires licensing and ongoing liability) for owners of luxury vehicles? If I was a business coach for electricians I would say it's not your job to make rich people richer. If you've got training, expertise and availability that is in demand, you should charge what the market will bear. If you don't think that's appropriate, maybe you should invite the electrician to determine much money you should be making.
