There are a number of “cheap” yet reputable providers in the unmanaged market, therefore it might be a good idea to consider purchasing management services from a third party (http://platinumservermanagement.com for example).
@SolaDrive – John, offers some of the lowest managed prices available, looks like they don’t require cPanel for management (which can be a savings if a cheaper panel like DirectAdmin or Virtualmin GPL will work for you). I’m not familiar with them directly but seems like it would be worth some research on your end.
