01. How many boxes of pokemon I need so I can maximize my 1 hour shiny charm (I plan to stack with donator status + link).
I would say about 300 eggs per hour, so in pc thats about 10 boxes. with the right setup, you should be fast enough to do 1 box per 6 min (during charm)
02. How much money does it cost?
it depends, can be the very first box or can be after months, my advice, be prepared with hundreds millions just in case
hope this helps
