Sorry for the delay.
@Ryan had some done within the last year perhaps he'd like to share (which reminds me of a conversation I had with him about a mistake in those brochures where I dropped the ball. Perhaps he has forgiven me).
There are several templates online but honestly not that impressive. A Google Image search returned quite a few examples. If you click on the image below (which indecently smacks of gimmicky Joe Polish) it will take you to the "SERP":
My Advice Would Be (for what it's worth)
Keep it very simple. Never to wordy. The average attention span of the American public is now lower than it ever has been. You only have about 15 seconds to make an impression and get a decision.
Definitely do NOT do want most CC's do and go on and on about "How awesome your equipment is." That is what you and "Tim the Tool Man Taylor" think is cool, but she (your client) couldn't care less.
All she wants to know is:
* Do they look professional?
* Are they thorough?
* Will they do their best and take their time with me or am I just another number?
* Are they concerned about me, my family, my pets?
* Will they be respectful of my home and belongings?
* Will they pay attention to the "little things".
* Are they good communicators.
* Are they reasonably priced (affordable). Counter to popular belief, she doesn't want it cheap. She's willing to pay more if you meet all her criteria because she finds it very valuable.
Lastly, she will make her decision emotionally and upon gut instinct.
You may have noticed a pattern. If you think it almost sounds like courting you would be correct. In fact, you could take old love letters during the American Civil War modernize their English and use them as your brochure and perhaps turn your customers into long term clients.
