Rpi reverse ssh to Virtual Machine

Job ID: 33010920

Budget: $30 – $250 USD

1) I have Raspberry pi with 4g hat and I need to have it upon boot reverse ssh into Google Cloud Platform Virtual Machine....
So
1a) I need to get a fixed IP address to a set in place Virtual Machine
2) I need to have it step by step explained to me how to copy and paste ssh keys ... that's been a problem for me
3) I need all the in between thingamajigs that are necessary to then run node red module on the remote, headless Raspberry pi that I now should be connected to.
4) need pi coded so that it will automatically reestablish connection if for some reason connection gets dropped.
5) And most importantly I need someone patient enough to go slowly and explain that to me as they do it step by step and I am watching and taking detailed notes.

I already have setup GCP Virtual Machine...and have fiddled with node-red a bit but I do not understand this ssh keys copy and paste business.
Thinking $60.00 to $100.00 for an hour+/- of your time.
