I'll try to answer as I've battled this in my mind quite a few times while redoing my service menu.
1st, pricing is going to have to be determined by your market, skill, etc. Doubt anyone can help you there without knowing your market, but i personally like to use $60-80/hr as a basis for pricing my services.
2nd, I decided not to use an AIO as a main basis in any of my packages. As i thought about it more, I feel the protection left behind by an AIO is inadequate as an LSP and that i'd be doing my customers a disservice by doing so without topping with something more durable. And if i'm going to want to put Klasse or Collinite as an LSP, i might as well just use a regular polish or compound beforehand.
My train of thought is, its more important to have multiple variations of corrective measures because of the multitude of different paint conditions you will come across. An AIO might be good for one car, but either overkill or underkill for another. After we Wash & Clay, we determine the best pad/polish combo to bring out the best end result, then lock it in with a choice of 2-3 good LSP options.
IMO if you marry just one product as a main basis of a detail package, your results will vary widely. I rather marry a result, and use whatever products i need to - to get that result. Then Protect your work. I have about 6 different polishes, compounds, aios - along with a variety of pads foam, wool, and microfiber that can pretty much handle anything. And a choice of Collinite, Klasse, Hardbody, Opti-coat as LSP options.
Unless of course you are a production detailer, paired to a dealership or autobody shop.
