Which router is good for t3 shared internet

Hi,

I am starting a new small business. We have bought 3 dell servers for our web application.
we have a shared t3 internet that is activated by the building IT people. Accoring to the letter they sent me after activiating T3 connection to our office..they said..they have given us 3 public static ip addresses with all inboud and outbound ports open.

We requested 3 IPs for our 3 diff webapplications.
I am not a networking guy and I have very limited knowledge about it. I was wondering which would be the best and cheap router that can manage 3 ips with T3 shared connection.

Any help would be really really apriciated…

Thanks,
