Sorry about the Signature not sure where to fill out at, I have always had to make up one lol
For the business I do one campers and r.v's we have our own business cards for them and probably do 40 - 50 of them a year. Now you have to remember that not everyone is going to pay top dollar for this service and when they do they demand the best service. If you search online you can find out what most people charge and see what you can get in your area where I live we have a very large vacation area less than 100 miles away and people call us to do them every year some 3 - 4 times a year depending on how much the travel around. Also if you search what camper and r.v's are the top priced ones this will help you in the long run as you will be able to get more money for the cleaning as your risk of possible damage increases, on the $1,000,000 rv's they have the smooth car finish that can easily be damaged with the aluminum wheel that they will want to be polished.
Also helps when you talk to campgrounds and they let you clean at there place "You will have to give most a kick back" to help pay for the water and letting you come in. But around here people will start doing them then stop because its so hard to make some of the customers happy "It's a lot different from pressure washing a house" there will be a lot more hands on removing bugs, streaks, hand waxing etc.
Hope this helps you, good luck!
