Custom OS VPN Setup on Raspberry Pi

I'm looking for a talented professional to configure a VPN on my Raspberry Pi 4 running a custom OS. The primary purpose of this VPN setup is to bypass geographical restrictions. The VPN should be able to provide DNS leak protection, and it should support multiple Virtual Machines connecting through the VPN.

Key requirements:
- Expertise in VPN setup using OpenVPN and Wireguard
- Experience working with Raspberry Pi and custom operating systems
- Knowledge of DNS leak protection
- Ability to configure the system for multiple virtual machines

I'm looking forward to receiving your bids!
