I've written and promoted hundreds of thousands of professionally authored words of my own which have helped me promote both my services as well as promote the offerings of many of my clients. Additionally, I offer my site for articles promoting the products of others and make available space on my website (note ads on the right here an other pages of my site) as a way of promoting client services, software, and other product offerings.
If you're interested in promoting yourself or your product on my blog in the form of one or more articles or with 6-month or 12-month long logo/link advertising terms, please contact me either through the contact form on this site by emailing me at brad (at) bradegeland (dot) com. For articles promoting your services or products, I'll promote them to my Twitter followers (which usually are retweeted to thousands within hours reaching many potential customers), to the 25-30 LinkedIn professional groups I belong to, and to a professional project management group that I administer on Facebook. Your information will propogate quickly to many eyes.
Let me know if you'd like to discuss further. Thanks!
