Based on what you said, it sounds like lack of technology isn't the problem here. The problem is more with the lack of interest in your industry in general.
Unless you're saying that by using technology, such as online services, it can increase your market?
For me personally, as a customer, I dealt with custom shops online that's halfway between new and old style with the "new style" being mostly on the internet with a page. I find these shops better since most of the time you can speak to the actual owner and they can do things just the way you like. They still do the old style "over the phone and paperwork" system by you calling a number on the website. The website looks straight out of 1998.
