My target is to not oversell my systems, what most people fail to do most of the time. Offer spam protection at no extra cost, means less server administration for me and happier customers overall.
My differentiator is that whilst I offer very small hosting packages, aimed at the small business website I offer a package addon which means they can pickup their phone and just ask for something to be done, a page updated, email address created, sent a backup of their site etc etc (this is within reason). My aim is to take out the worry of maintaining a website for the new user, and allow them to focus on running their own business instead of fiddling around with a hosting control panel.
