Best Opener Installation in Phoenix AZ

Emailed for a quote with detailed information about what needed to be done. Jennifer the Office Manager wrote back with an hourly rate but also said "we can set this up for 8 hours." Confused because of the lengthy time I was quoted (3 faucet installs and towel racks shouldn't take 8 hours), I inquired about the estimated time that I would be billed. She repeated her original email saying "we can set this up for 8 hours." Not helpful. Would not recommend.
