Help me with Marketing

I'm starting a private nutrition coaching and fitness business in a regional area. I'm a qualified nutrition coach and fitness instructor/personal trainer. I need some hard copy marketing material to distribute, initially I was thinking DL size brochures. I'm stuck on what the hell I should say and how to say it, nutrition and fitness is such a broad area. My target market is people who are overweight and/or have diet related health issues. I want the emphasis to be on nutrition coaching with the fitness as hand in hand or secondary as far a services offered goes. Currently I'm not set up to do studio style personal training, that's further down the track. With the minefield of information out there surrounding nutrition, I want to be tell people I can cut through the confusion and implement nutrition plans specifically designed for them to help them achieve their goals, whether that be weight loss, regaining their health or just eating more healthily. Couple this with a healthy lifestyle (fitness) and they can turn their life around. I like to take a holistic approach but don't want to come across as "new age" or airy fairy. People in this area are only just starting to leave a very conservative thought process behind. Hard sell copy will defeat the purpose, my prospective clients will not respond well to that, it needs to be clear, concise and compelling..."I need this".
