We would like to welcome you onboard at
XenLayer.com, feel free to check out our range of OpenVZ and Xen VPS servers. I would recommend an OpenVZ 1GB plan with an IP addon. Our highly advanced control panel allows you to split your websites over the IPs you have, the service is fully managed, which means we worry about your uptime load and security, while you handle the rest. Just like you are used to, except you have everything on one hosting plan, at one company, and you have full root/administrator access to your virtual private server.
Edit: On request we can install a Wordpress auto-install script for free, one click installs for all your (future) blogs. Migration is also free of charge, cPanel, DirectAdmin, Plesk, not a problem. We will take care of it.
