Why not go with a cheap Dedicated server instead of a vps? Just throwing that out there.
You only seem to have 64bit versions of windows as an option and of the cheap ones , the highest is a Pentium-D ... anything less than a Core2Duo isn't going to be 64bit. So right there someone would have a problem with your order form. And your core2duo starts at 189$ as opposed to nearly half that price over at wholesaleinternet.com (Windows 2003 web is only 15$ more with WSI can get a Core2Duo, 2GB rams, Windows, 500GB hdd, unmetered 10MBit or 1.5TB of 100mbit, 8 IPs, for around 100 a month).
