Mid size commercial estimate help

This is for an exterior clean.

They gave me access to a 40ft lift which they will operate. Twice a year.

I have a 32ft ladder and an ezpure mini wfp which can reach around 30ft.

2 questions. With the equipment listed am I equip for the job, and how much would you charge? I was thinking 2-4$ per window. 4 for anything above 1st story. I’ve never done this level of commercial. Only high end resi and storefronts and my bidding tactics for those don’t apply here
