Zabbix post-install customize, discovery, inventory and alerts

I already installed Zabbix. It's working but now I want to customize it for my environment and have someone remote screen share tutor me through the features and functions, integrate it with network devices like firewall and switches, add to Inventory, deploy agents, see what's the difference with network discovery and setup alerts, including SMS. This is a project only for a Zabbix admins who works intimately with Zabbix on a daily basis. I'm thinking 2 to 4 hours. Let me know your hourly rate, pls.
