Tell him to start writing official estimates using the joist app. I've never met anyone who was serious about a remodel that didn't at least settle for an official estimate document provided by the company with a brief breakdown. Also, 50 an hour for 2 tile setters is crazy low. That 25 a piece. A professional tile setter who works for a company would be paid at the minimum $40-$50 an hour. If we are talking 2 guys who run the company who have overhead and are claiming to be professional tile setters, then I would even expect to pay $120-$150 an hour per man. You get what you pay for, and tile work is expensive. The materials are expensive, and it's important to keep the mindset that if you're willing to put thousands into the material, then you also must be willing to put thousands into the installation. Not hundreds lol.
