Hi, Why don't you wash it yourself. All you need is a hose attached to faucet, a bucket, wash and wax rv soap, a brush with a long handle(buy it at Walmart). Wash a section at a time and rinse. After coach is washed use an old towel and dry it using was brush with towel wrapped around it. The following day buy some Protect-All(at Walmart or camping world) spray it on a piece at a time and rub it in a circular motion and if you want you can go back and buff it. The best way is to do a side a time however I do the whole 35 foot coach in one day.
After you finish get a cold beer and enjoy the way it looks.
