Linux open source Full KVM virtualization help with proxmox

Hi There, Looking for someone who has done a lot of work with linux and proxmox. We need to setup the server with all updates ( we user web proxy for internet access ), backup - Schedule containers backup, host backup to network NAS, explain what we need to do in future when we will add this in cluster environment. Need you to document the setup as once it's done we can follow it for building next server. we have 64 bit 2 physical socket CPU, raid 1 2 tb and enough memory support. I will get initial installation done, you will do high configuration and make sure everything nicely setup and secure. Let me know if you have any questions. I am expecting it'll take about 4 hours of your time.
