You shouldn’t realistically expect to charge customers according to value delivered to their company. You’re still selling services on an open market, competing against other contractors and their pricing.

Nobody is really interested in handing a services provider more money than necessary to get the job done at market rates, so even value-based bidding ends up coming back around to market rate pricing.

You can always ask, of course, but at the end of the day any rational company is still going to evaluate your proposal against their other bids from other contractors.
