Trust is everything in business, clients are prepared to pay more for a trusted service. Why do you think so many clients are prepared to pay professional fees when they could easily find someone to help them who won't, trust!
If you write a monthly message for your clients, I strongly recommend you do, (they take only 15 minutes to put together when you know how to) the trust you're continually building could be enhanced so that all your future prospects can benefit too.
You can do this by placing your monthly messages on your own blog. My blog's cost me around $8 per month, I actually have 2, Free Referral Secrets for my business clients and Improvement After Movement for everyone.
The Improvement After Movement blog is more of a hobby at this stage, I save about $500 per month with sponsorships from my physio and chiro, they've been helping me put my body back together so I can play sport again.
The I AM (Improvement After Movement) blog gets hit between 2000 and 3000 times per month, it looks like it could be pretty big. Check out both blogs if you want to get a feel for how I leverage my time.
Blogs are basically an extension of yourself, they build trust 24/7 so you don't physically have to.

You'll see my blog's act like a website and blog, the homepage stays the same, the blog is in behind it, you'll see what I mean.
