i also agree with adding the phone line it would make it easier for people to speak directly with you which gives them that feeling that if they need anythinh they can pick up the phone and maybe see results that day. i would also try to advertise what you have now a bit more i know for the time being you are trying to reamin small and somewhat semi-private but i think people your name out there for more people to see wouldnt hurt things at all. and with the addition of the phoneline they would be able to pick up as soon as they see the ad of banner and find out more info from the owner himself.
one thing i also thought about was if after you get going and business is going good and you are making a somewhat decent profit that you could think about buying the additon to make your dyno an awd dyno. it would bring a loager market your way and would put you on top of everyone else in the industry. i know 65k is alot of cheddar but from the looks of it the market for it seems to be there and might be worth the hefty pricetag. i mean hell there are people willing to drive to maryland for an awd drive dyno so hell i am sure they wold be willing to pay for a spin on yours and be gratefull for it and would more than likely would spread the word. which in turn would bring mo money mo money mo money your way
and jp i ment that having patience and knowing it is half the battle i am not a total retard.
