Review Linux Cloud Systems Configurations

We have setup a Cloud based service using CentOS platform and Enomaly.
GlusterFS is used for the storage nodes.
The system is up and running but I need to ensure it is working properly.
One of my main concerns is DHCP provisioning of VMs.
Currently experiencing issues with provisioning of VMs which may well be down to DHCP issues.
One of our nodes seems to be uncontactable after a period of time - needs troubleshooting.
I\'m after someone to work closely with me to advise on current setup, best practices and iron out some of the issues we are having before we can use the platform.
Knowledge of Enomaly a huge advantage, as is Gluster FS.
Linux knowledge essential.

Looking to start ASAP (today if possible!)
Payment will be on an hourly rate worked rather than for the complete task as there are multiple tasks to complete.
