Asterisk Expert for long term project

We are looking for a long term relationship of Asterisk Expert. Must have expertise of using Asterisk as Premise Based PBX. First contract is re-factor and support of 4 Asterisk Installs. Each Installation is Debian Linux host with following: 1 x 4port Digium Tormenta or 4 Port Sangoma Card 4 x 24 Port Channel Bank (FXS/FXO) combination 1 x Digium E1 card for inbound PSTN connectivity 1 x Flash operator Panel 1 x CDR Stats Report Tool 1 x MySQL install for CDR 1 x PHP install to support MySQLAdmin, CDR Stat. The first contract will simply be refactoring and documentation of each configuration to make all 4 systems look similar. However, each system is unique due to the specific Dial Plan. This will account for about 10% difference between each of the four deployments. Please do NOT respond to this ad unless you have DEMONSTRABLE experience installing Asterisk as PBX for at least 5 locations. This is expected to be a 10-20 hour job depending on your skill level. Thanks
