Example: My neighbor. We were visiting last night, when he tells me: "When you first told me what you could do, I had no idea what plasma cutting was. When you told me, I said 'Oh, yeah, that's neat stuff', because I didn't want to sound like a dumbass. You said yard ornaments, so I thought 'Oh, he can cut flamingos and stuff. Good luck with that.' Now that I see some of the different things you can do, this is awesome!"
I was showing him the mock up of an original design last night, and he was very excited about it. He owns his own business, which caters to the upscale clientele in the area, and this design is based on a dock requirement here at the lake. His words: "My clients would eat these up. I'll be happy to hand out brochures or flyers or something for you. Once one of them has it, the others are going to want it too."
I'm trying to come up with a business card design that can convey capabilities, without being too busy or overwhelmed. I'm thinking it will involve photos of some cut artwork, as well as photos of more "industrial" cut pieces. While not these exact photos, I'm thinking something like this:
and something like this:

Unlike a web site, where you can add additional images, links, etc, I think a business card needs to be extremely economical in conveying who you are, and what you can do. I also see business cards being left at businesses (Airgas, steel supply shops, welding shops, fab shops, etc, signage, etc), whereas the general public may be exposed more via Craigslist/Facebook/Etsy/Pinterest/something their neighbor purchased.
Those of you who feel you've created a successful business card design, I'm curious what you've done to convey your capabilities in this somewhat oddball area we operate in.
