Node setup for multiple blockchains on a ubuntu server

Job ID: 32337229

Budget: $250 – $750 USD

Like the title says, I need someone that is able to install a node from different blockchains such as BSC, AVAX, FTM on a powerful server running ubuntu.
I tried myself but I find it too difficult.
You would also need to explain to me how to connect to each node (creating different users), and how to maintain those nodes and to sync them as I probably won't be running them all at the same time to save up bandwith.
