we got a price quote on a 50KW 3-phase diesel generator of 18K and some change including transferswitch, but not-including labor of install. what would be a decent mark-up on this item, we submitted a quote to our customer that included a 20% MU +6% tax. the customer seems like they are going to have it done for the price quoted. for Future reference, do you guys feel this was too high? or about right?
