Dejamatt has the best info for your sending behaviour in this thread - so i suggest you bear what he says in mind when you setup and start sending. That said, you will still need a system that can do the sending. I can help you with that, I have many systems running and available depending on your sending requirements. Here is a rough outline of the spec that you would need:
Multiple offshore servers (inc main server for data and sending servers - that way if sending server goes down you don't lose any data)
Multiple IPs on rotation - all C Level with a reputation of 90-100% - with 60 IPs you can send 500k - 1 million daily
Easy to use Interface
Then you will need someone to manage the Admin, Spam Complaints, IPs, Bounces, Reputation and to provide support and consultancy on your list management, sending and content to ensure that you keep the reputation of the IPs where it should be.
Let me know if you need any more info, feel free to drop me a line, I can't PM on here yet
