I am a US (west-coast) based Linux SysAdmin (prefer Debian & Ubuntu), with over a decade of experience. I've deployed Asterisk systems ranging from 2-person offices, ~20 line call-centers, and my largest deployment had over 120 phone numbers. I currently manage a number of Asterisk installations, and would be happy to setup this environment for you; using web-based tools that will, by the completion of this project, easily enable you to take over day-to-day management tasks.
