Whoa. This tree service clearly only wants business if you don't ask "how much?" Wonder why? Well, their resale lumber for sale is 2-3x more expensive than market -- Imagine what the cost of their labor would be.
Imagine -- yup, that's what you will have to do. When questioned about providing pricing we were called "morons." Even better, they committed it to an online message, so it will be memorialized for all to see.
Stay away!
