advice on brochures

I am recently a new independent IM/SEO. Since I am starting, I thought a brochure may be a good thing to put together, especially since I will be hitting up some upcoming conventions/trade shows etc as well as to hand out to other local businesses. My thought is that it exhibits a certain amount of credibility(shows that I am a serious/honest business/consultant) at least.
Id like to know what, or if any experience others have had using them. Any suggestions on a headline for the title that may entice business owners to open it up and read. I have most of my material together but am trying to think of a good headline. As of now I am thinking of using the headline "whats wrong with this picture" and have a pic of an unhappy business owner or even a pic of a happy business owner giving the thumbs up (picture in contrary to headline provokes interst is my train of thought), or something along those lines. Any thoughts, suggestions, info is appreciated.
Thanks.

I would cater the title more towards your niche. I saw one that said "Increase your business revenues three fold with a method you never considered"

It was pretty effective because it drew curiosity. Enough curiosity to grab one an open it. Offline marketing is the same is online. The goal is to either, A) create curiosity or B) present a DIRECT major problem.

In this case, you want curiosity so that they take one and open it.

Thanks for your input. Being more niche specific is something I have been thinking about. Id like to target small to medium sized business owners. I have not targeted any specific type of profession/occupation and was trying to attract the general business owners. This is part of why I posted this looking for input from members here. Thanks again. I am certainly open to more info and feed back.

Stop thinking so hard, the work is already done for you. Just look at your competition. Google the term "swipe file" and you'll start to see the light.

I second doing a quick look at the competition, it will help get your mind brainstorming. You want to intrigue them and get something to prod at their curiosity. Make sure it?s also bright and eye-catching so you get their attention.
