Here is a portfolio of featured WordPress sites for which I have done work. If you would like more information, simply click the button below the site and you will be taken to a larger screenshot, a bit more information about the site itself and a link to the current site.
For quite some time, I've been recommending Bluehost as a hosting service to everyone who will listen. They have a great product coupled with great support at a great price.
DISCLOSURE: Now, I have the ability to offer it as an affiliate. If you sign up for a hosting account by clicking a Bluehost link on this site and stay for 6 months, I'll be compensated for the recommendation.
