I have found the following services to be invaluable in growing my business.

Aweber: email, autoresponder and newsletter marketing software.  It's best to start with one company and stick with them. I outgrew two different newsletter programs and when I changed over my subscribers, lost hundreds of names.  Don't make the same mistakes I did.  They offer outstanding customer support and ideas for building and maintaining a list.

http://www.selfgrowth.com  Gary Craig has selected selfgrowth.com to list only certified EFT practitioners.  I highly recommend listing yourself here. SelfGrowth.com is a huge directory, with articles and references to thousands of other Web Sites on the World Wide Web.

AudioAcrobat  I resisted moving to a paid recording service for a few years but realized I was only limiting myself.  AudioAcrobat is an easy way to record calls, make audio and video productions, send links to customers, imbed content on your website, etc.  When you are ready to move to paid audio products, this is the company top EFT practitioners are using.
