"Request a quote" is a sign to me that the company is dishonest, with high pressure sales tactics, toxic incentives, and a culture of maximizing profit over providing quality service. I've never seen a counter-example of an awesome, high performing company I loved working with, who went the extra mile, use "Request a quote" or similar tactics.
"Request a quote" is a corporate version of a street busker con, with them needing to get up close and personal, to shuffle the numbers and dazzle you with "here's what we are willing to do, just for you!" as their hand slides into your pocket.
There are always better options that somehow manage to be honest, clear, and upfront with pricing. If a company is hiding the price, it's to get away with something that you'd call out as sketchy if you knew all the information in advance. Even if it's only to force an interaction with a skilled sales agent, it's a despicable tactic.
