I agree with Nick,
Keep it real simple using a one-step cleaner/wax and the Flex 3401.
Don't do show boat work, just slop and glop work.
I do think you're quality of work is too good for this type of work at this price so it comes down to you and if you want the job. I know it's hard for perfectionist to not give it their best.
If it might help you to get more and better marine detailing jobs that's an extra aspect to the job that might make it worth it to you.
Rememberer I also teach cherry picking, that is put your focus on customers willing to pay more for higher quality work and let someone else have the less profitable jobs.
Also, you need to see the boat first. You want to see whether if the inside of the boat is condition #1, #2, #3 or #4.
#1 = New like new
#2 = Light oxidation
#3 = Medium oxidation
#4 = Severe oxidation
You also want to gauge how much non-skid there might be. The more non-skid the lest surface to wax. Also, vinyl seating. More seating, less waxing.
