We've done details at our ss wash in the past. The beginning was great, had a self motivated guy that was experienced at detailing, we supplied the space, insurance, tools and supplies and he scheduled, detailed and met with customers for the pickup of their vehicles. We set the pricing for services together and we got a small percentage of the job to cover our part of the agreement, he kept the rest and whatever tips. He was also supposed to help customers and keep the bays clean. It was apparent that the car wash stuff was too hard for him to keep up with and detail 3 cars / day, so we hired separate car wash help and left him to his details. This arrangement worked out great for a while, he needed the work and it was a nice income generator to our car wash. However, after things got rolling along and schedules were flowing, he had some money in his pocket, didn't need to work anymore. So we were left to finish out his commitments because they were our customers also. The first guy was really good and could handle 3 or so details a day by himself, but for some reason just let it go. We then tried to replicate it three subsequent times with other "detailers". Our experience was that other people who claimed to be detailers, were not nearly as detail oriented as they needed to be or simply worked too slowly or needed us to tell them what to do next all the time, or they couldn't manage time/ schedules. So the payout was not good. All in all the failure of each detailer left us to finish up their schedules and we simply couldn't do it all ourselves. In my opinion, for this to work, it absolutely takes the right individual who can manage all the little nuances to this business and won't quit in a few months. It's very hard work no doubt, but very satisfying also. I think most people who get started in it only see what the payout can be, but don't realize the amount of labor involved. It's massive. Very few people bring "easy to clean" cars to be detailed or they would do it themselves.
