Optimise current Zenoss Setup | Ensure ALL Nodes are SNMP monitored

Hi Service Providers, i currently have Zenoss setup but it is not optimally configured. Zenoss is currently monitoring sbs 2003, win 2003, Cisco, hp procurves, cyberguards and other SME kit. There are no more than 20 nodes currently been monitored. i require a service provider to configure Zenoss to ensure nodes are been monitored to their full potential. I need it to monitor the hardware, OS, software components, CPU usage, memory, hard disk, etc. It would also be ideal to have the GUI setup with graphs created and alerts to be sent when thresholds are exceeded. The chosen service provider should have experience in installing and setting up Zenoss. Mandatory to have strong linux, system administration and network management experience. This project should be quick and easy for the right service providers. LOW BUDGET for this project but opportunity for further work. Please contact me if you require any clarifications via PM. I like questions :) Regards
