jabber server setup

I am looking for someone to install and configure a jabber server on my website that i am trying to use as a mail service at some point in the future. i want to be able to integrate all the other chat clients inside this mail interface and i need jabber to be setup in order to do so. I am looking for someone with extensive experience setting up such a system on a linux box. thanks and i look forward to hearing from you. Cheers.
