I think some of the top name taxi's take in more then they can chew hence the long wait. But some people dont mind.

Heres the catch...we take in what we can do in a year the very first season. From there, if our work is something others like, more work shows up. So, we can...1) keep raising the price to adjust the numbers that come in, until even good customers cant justify the price, or...
2) turn people away, including good customers who "shot their trophy too late" and offend someone, or...
3) quote longer return times in hopes that some folks will say WE are****ing nuts, and go elsewhere.

See what Im saying? If your work is sought-after, you cant turn them down. I tell my customers up front how long its going to be. I tell them its at least this amount of time, or more. I used to get in trouble when I wasnt up front about it, or went way over what I did say.

Its not an easy solution, but the decent customers will understand, if you give them something worth waiting for. If theyre only wanting a nice clean commercial mount, theyll go elsewhere and be happy there too.
