Dear Friend!
If you are reading this letter, it means that you have already chosen me as your task performer. I am experienced in System Admin, Linux, Asterisk PBX, VoIP, Debian. I promise that I will manage to do your task much earlier than you expect. And of course, I will do it with higher quality than the other performers. So, in order to start, I am waiting for the details from you ASAP.
