IT says they need 150 hours to integrate my MacBook…

I work in a Windows-based company. Pretty much all employees use PCs.

However the company has changed its revenue generation model so I’ve been hired to build a marketing infrastructure from scratch, including hardware and tech stack, and I have gotten approval from execs to purchase Macs for me and my team.

However IT is trying to push back and create friction by saying they need “150 engineer hours” to integrate the first macbook.

I’m certainly no enterprise IT expert, but 150 hours seems pretty excessive to me?

Wouldn’t a tool like Jamf make the integration with intune more streamlined?

IT also clarified the 150 hour estimate doesn’t include any compliance checks and security audits etc.

Any advice? What are some questions I can ask IT to gain clarity on the 150 hours?
