Hey there, Avidity!
I want to add my proverbial “two cents” in on your topic.
If your pole extends to 33’, with your standing height, you should reach those upper windows easily.
However…The staining to me looks like a heavy combination of residual buildup from neglect, just on a larger scale. My FIRST advice to you is this: Buy some “One Restore!!!” This truly is a near-miracle working solution that will make your work life much, much easier. “Scrubbing” this type of residue off is not a task you want to undertake without this secret weapon.
I seek out the most difficult, filth-covered, caked-on, baked-on windows in the Tulsa area, and turn them around with proper use of “One Restore.” Be sure to read the instructions carefully. Your only issue here to circumvent with One Restore at your side is to safely spray the detergent at your upper heights. Do you have a telescoping ladder that is at least 24’ in height? If so, you can load a sprayer cannister (Hudson brands I find to be the best and spray steady patterns, even long distance straight streams up to 18’ to 20’.) with One Restore (have your water hose hooked up, sprayer on and tested, water source at full capacity PRIOR to spraying the solution. If you have to climb and spray, wear safety goggles with vast coverage and a cheap respirator/surgical mask also. The chemical stings the skin and burns the eyes due to the small amount of sulfuric acid. Saturate your WINDOWS (not the frames around it, as the solution, if left on too long, will discolor the frames…) and rinse all of those years of buildup away in seconds. It is remarkable. It will save you hours and hours of scraping, buffing, and hard core, shoulder-heavy cleaning.
USE THEIR LIFT!!! What a gift to have. Getting your nose to the glass will make your work a bit slower, but ultimately the best that it can be. Nose to glass! It will also help immensely with your One Restore treatment!
And finally, your bid…This quote prices your panes at $7.57 each. Are you cleaning the Interior AND the Exterior? If Exterior only, your bid is too high. If Interior and Exterior is being serviced, you are still high, in my opinion. Do you have competing bids on this work? How did your client react to the initial bid? Will your work be recurring, or a one-time cleaning? These are vital questions.
The approach I might take, especially if there are other bids (for them to offer their scissor-lift is a great sign that you may have the job already), is to price the windows in the future, or in a re-presentation, is to drop the price due to their offer of use of the lift (We HAVE to justify price drops!!! Dropping for no reason is asinine, and makes us look like hungry, desperate scavengers that will drop price in a second. This rapidly diminishes our credibility AND our profession, so I pride your pricing in that regard), and price the windows PER buildup and height in this scenario…for example, "…Mr. Client, your 3rd floor windows, which total a complete count of 98, have extreme buildup on them. They will call for a “restoration” treatment to “bring them back to life.” You have justified the pricing with this (as you did with your $150 add-on), made it clear to the client that this is highly professional “restoration-quality” work, and go from there.
Sorry to ramble…please reach out with any questions. I have done numerous projects like this one, and have learned by much trial and error. Let me save you the mistakes I made.
Good luck!
