If I get told to 'ask the sales team for a quote', then sorry, I'll find another product or service that just provides the information up front. Would I be willing to pay their prices if I talked to the sales guys? Maybe, but it's still an extra inconvenience that's easier to avoid than go along with.

And no offence, but it's very unlikely your product or service is that unique that there's no viable alternatives out there. That don't waste everyone's time.
