I find the way I am best able to get the price I charge for a detail is to educate my customer.
That's my job. Differentiate my quality of work from that of others.
Some people want quality, some want a low price.
Those that want a low price can often be educated to pay more once they understand what they're getting.
Educating involves,
The high quality products you use, versus the less costly products your competitor uses.
The human element of Care, that you put into your work.
Most of my customers know I'm not polishing their paint because I need the money, I'm doing it because I genuinely enjoy polishing paint. It's the fact that they know I enjoy my work that translates to them that I care about the quality of my work.
Anyway, you need to do the same thing.
Educate your customers.
Differentiate the benefit of using your services from those of your competitors.
Also, educate your customers on their car's finish. Most people have no understanding or knowledge about their paint. That is how thin it is, how susceptible it is to scratches, swirls, and dulling, and how hard it is to remove scratches, swirls once their instilled and restore clarity and that it takes experience and the right tools/products to restore gloss after the finish is dulled.
A lot of new car salespeople tell people that clear coats don't need to be waxed. Educate your customer that this is wrong and that clear coats are simply clear paint, i.e., resin without pigment and they still require regular maintenance in order to maintain their good looks,
Show your customer that you are an expert on surface coatings, and they will trust you with their paint, especially if the car is more than a daily driver, (at least to them).
Again, this is where you relate your knowledge of paint, (and other components), back to the high quality products you use.
In other words, you don't use detergent soap to wash your customers cars because while it may clean really well, it is to harsh on the paint, vinyl, rubber, etc.
Educate.
Your first day on the job, make sure you do a stellar, first rate job, do extra little things if you can, and create a flyer that details what you did, what you used, and other services you offer, or whatever…
Definitely put up a website if you don’t already have one.
FWIW
