VPS Hosting Required (cheap and reliable)

[Glaceptra]

Can someone describe their VPS hosting signup methodology. I'm opposed to fully automating the process. I'm too the point, we want to take orders, but worry about the spammers using resources before a follow verification check can be done. We feel our network, redundancy and planning are solid - it's the next "step" to get orders. Suggestions?

We're basing our offering in 4 plans using Xen on 5 hosts, mutipathed ISCSI (2) SANS.
