I agree that this isn't really a pricing problem (more value proposition, sales, etc), but pricing may help fix the challenge. There's not enough information provided to give definite answers, but I would suggest a) offering a choice of pricing models (outright purchase & rental immediately spring to mind) b) offering choices within those choices, where applicable (e.g. 12 / 24 / 36 math rentals) and c) creating a decoy product (like the $A24k Apple watch). If someone buys it, great, if not, it makes every other product look great value).
Happy to chat further on this
