Thanks to everyone for their suggestions :goodjob
I really like the idea of mailing cards out to my customers, that is a very nice touch. That does mean that I'll have to start asking for people's home address since I often do their vehicles at their place of employement, but that is a really good way to keep my service in their minds.
I'm going to be approaching some golf courses, especially since my wife cleans the house of the manager of 2 very nice country clubs locally. Hopefully that will give me a way in.
Car clubs seem like a great way to market. My only concern is that, from my experience, those are typically the guys that do everything themselves and won't let anyone touch their cars.
I guess I could try mailings in more affluent zip codes, however I'm not sure if I would get a good enough return on that investment. I'm not averse to going door to door in such neighborhoods, but most have a strict no soliciting policy, many including no distribution of any type of flyer. I'm not exactly sure how to reach them.
At one point in time, I offered excellent rewards for my customers that referred me to other people. However, it never really produced any good results for me. I find that the people that really like me and appreciate my service will tell people anyway, and others that kind of take it for granted aren't going to put any effort into telling anyone regardless of what I offer them.
There is another company locally that is running an advertisement on a local station for advertising, and I was approached by a guy the other day while filling up my truck about it. He thought I was that guy. I told him that I wasn't, but I'd be happy to detail his Harley Davidson, and went into what I could do for him. I lost him at the price. Then I had another guy approach me in a parking lot while I was eating lunch in my truck, and he too thought it was a great idea, asked what I charged for a full detail, and then practically ran after hearing the price.
I guess what I'm taking away from this thread is that I can't really change the perception that people already have of this business, but what I can do is take advantage of targeting those that may already have a better perception. Up to this point, I guess my marketing was just aimed at anyone that would be interested, and in being all-inclusive, I may have alienated those that were looking for something more "special", or catered to them. So, I will look harder for those that would be able to afford my services by tailoring my marketing to them and going where they go to do so.
Thanks again!
