Ya very low prices... you won't be making any money and you will burn yourself off.
Consider that you have to spend time going to the customer and back. On average for me that is 1 to 2 hours commute for a detail.
Then you have to setup your equipment and put it away, at least 30 mins total for that.
When you get home you have to wash microfiber towels, clean your polishing pads, and all that maintenance stuff.
Then you have to do the accounting for your day.
If you are making 20$ per hour on the job (which by my calculation is about what you are gonna be making), after all the extra stuff (not counting time you spend on the phone with customers and the time to advertise) you will be lucky if you make minimum wadge.
I would strongly suggest you re-evaluate your pricing!
