How much would a crypto dev pay for good security auditing?

Hey all, curious how much crypto developers pay for good audits before they launch a huge protocol. Obviously, you'd want to spend a decent chunk of money to prevent large stolen flows. I've heard of sites like Code4rena and Immunefi, but I'm talking some sort of tool that analyzes your entire compiled repo and returns a huge mountain of issues from several different bug classes with the intent of mitigating potential critical vulnerabilities pre-deployment. The audit should include mitigation steps and dynamic exploit generation.

All answers are greatly appreciated! This is just to better understand my fellow developers as I don't want to (a) overspend or (b) underspend on this class of tools.
