Network config files for Ubuntu 16.04/18.04 (inclusive Netplan)

Attached you will find a simple diagram about my basic Network configuration. Basically it consists of an Ubuntu Server Host with two Ubuntu Server Guest VM's. The host has one physical interface with one single IPv4 address and one IPv6/64 subnet from the ISP. There is an additional IPv4/29 subnet routed to the same interface that can be used for the VM's in a routed setup. What I need are the configuration files needed for the host and the guest systems. Host and/or Guest might be running Ubuntu 16.04 or Ubuntu 18.04. I need the config files for the traditional systemd-networkd configuration as well as the config files for the new Netplan/networkd configuration. You must understand the difference between bridged and routed setups. The config must be a routed setup since the ISP does not allow undefined MAC addresses (from bridged VM's) on the physical interface. The configuration must include the static configuration settings for the host and two VM's. The host gets it's IPv4 address, the IPv6/64 subnet and the hosts IPv4 address from the ISP. Each guest VM must be (statically) configured with one IPv4 address from the IPv4/29 subnet and two IPv6 adresses from the IPv6/64 subnet. Optionally the IPv6 address space is further divided into IPv6/80 ranges assigned to the hosts. As soon as I accept your bid I will send you the IP address details from my provider (address, netmask, gateway, broadcast). I expect 4 configuration files from you. I'will make a copy of the files from the first VM for the second VM and modify the addresses accordingly. If you know what to do the job can be done within 15 to 20 minutes. I need the job be done as fast as possible. Don't hesitate to ask in case you have further questions.
