Just thought I would add my .02...
We ALWAYS encourage our customers to drop by see what we're doing and how we are doing it. We have an "open door" policy, if we are here ... your welcome to see what we are doing.
We have a lengthy conversation about EXACTLY what it is you want to drive away... and then we put it writing on a work order and everone gets a copy.
We charge a 1000.00 deposit, with the remainder due at pick-up.
No pay as you go ( unless it's a complete build with a year or two build time... and they do happen from time to time :) )
As far as pricing... most of the time the old axiam is true "You get what you pay for" Our average drive away pricing is around 4,500 to 5,000... that includes our back-half .. with everything included.. ie; 12 gallon tank, 2 450's or equivalent, 8 1/2 valves yada yada yada... Front done... all laying on the deck of course.. :)
Anyway... Hope this little statment helps you find your way thru the darkness...
