Amerinoc is the right choice.
Their own staff, onsite, 24/7, all day, everyday. Low priority tickets are answered within 10 minutes or so and I have never had the need to submit any high priority or emergency tickets.
You get a great discount for paying 12 months upfront. No need for ICQ, just use the "Live sales" button up in the top right corner of their site to talk to them directly, my last dedicated was fully setup and functioning within 2 hours from my payment, and that was on an American Holiday.
I can not express my love for them and all that they do for me enough, without them I would probably not be in business. Truly worth every penny!
