im sure there is a shop around you that will do it and do it right.
as for a price, depends on which series the PMS is and what else you have to go with it (MAP sensor, software etc).
you may want to just invest into a wideband o2 sensor (innovate motorsports has good ones for reasonable prices) and tune it yourself. thats what i did and it worked out well, i never have to pay for a dyno tune again. and at $500-$600 each time buying the wideband and learning how to use the PMS has paid for itself many times over.
