We use World Wide Technology (WWT) for all of our Cisco purchases including the SmartNet warranties. My salesman's name is Keith and his number is 1 (314) 919-1513. I'm not sure if it makes a difference if it's for personal or business use.
Cisco makes no distinction between business and "personal" for SmartNet.
You can ask Cisco directly (don't expect them to care for such a small purchase) or any Cisco certified reseller/partner. CDW sells smartnet contracts, but you might get a better deal through a local reseller.
