I just read a post today on Autopia..a man in the car detailing business decided to share all his form, checklist etc with anyone who wanted. Thats something you might want to look into.
The main thing you need, first and foremost, is a good jack stand.
Based on you own bike, get a good idea of how long it takes to do a wash only, a wash and wax (or seal) and a full out, nothing missed detail (to this one add one hour). Then very precisely decide what you have to make an hour to pay everything and still make the profit you want. This will give you a good base to work from.
As far as vendors to buy equipment. There are a lot I have had to go through to get/make what I need. Any specific question for that I can answer in a PM.
Pinnacle Paint Cleaning Lotion and Souveran should be on hand.
Detail Paradise MF Skinny is the absolute best applicator there is for bike details.
EZ Detail Brush will be your best friend...I am big on cross-contamination...we used three dedicated ones on bikes (wheels, motor, frame)
I do not like (actually hate) the use of air compressors (way to much pressure for seals and gaskets) and weed blowers (exhaust pipes) for use on bike. Get an Air Force blower.
There is tons more..so feel free to PM me at anytime.
HOGtailing is my business
