I good option will be ThePlanet (http://www.theplanet.com/)
Their server sales website is: http://www.servermatrix.com/
I'd really recommend you read thru the site, it is full of detailed
information about everything you might ever need.
PS> Traffic is not a problem for them and the machine prices also meet your needs.

Have a nice one.
