Hi:

I would never have a sign out front at shows your pricing. That's like playing a game of poker and showing your hand before the flop. Let people know who you are first. (i.e. let them know that you are a contractor in the neighborhood) Landscapers do it, pavers do it, pool companies do it etc.

People who are passing by in the neighborhood that are curious will know that you are a detailer will formulate a conclusion in their head....(Maybe I should get mine done? Mobile detailing, that's cool!)

Business Name
(description if necessary)
Phone #
Website Address

Keep it simple. The rest comes down to your sales abilities. Additionally, when you bait a customer for the "low prices" (i.e. detailing prices starting at $49.99!) You are limiting your ability to get customers who are willing to pay for a high quality service. Unless you plan on doing serious volume keep pricing as far from "standard" as possible.
