While we don't use Cpanel, We do you use Directadmin which is much better than Cpanel. I can get you into or close to those specs on A VPS for around $70 wich comes with full management, backups, free site migration or a dedicated server starting at $100 depending on the CPU you want . Both plans come with full 100Mbps unmetered port.

Here is some real life experiences from clients of Amerinoc (formerly phatservers), none were paid for or bought drinks for at a convention.
