Know-How Exchange : Advertising/PR

The "limited budget" thing is very telling. It says that getting the word out about the benefit isn't worth much. If it were, you'd be able to borrow the money to invest in the education process, with high likelihood of repaying it in short order.

My guess at why: I suspect that the cost (or commission refund) is not the primary benefit your customers seek. In fact, cost/price isn't really even a benefit. It's a feature.

You need to dig deeper and identify the real reason people might want to trust you and become clients, and then promote THAT benefit. They'll figure out the cost thing on their own ... once you sell them on the real reason they should do business with you.

Since you said your existing clients thinks that what you do is fantastic, why can't you explore a referral campaign inviting your existing customers spread word about your service and announce rewards for every lead (or conversion) they bring. You can do a simple e-mail blast to announce this program.

You can even provide them a customizable mailer which they can use to spread the word making their effort of spreading word easy & fast.

Write and distribute articles to industry publications (although they may be reluctant to let the secret out!), article databases and present the story with substantiated data to business writers who may want the "buyer beware" angle.
