I will first SE the GPU on their main site and the rest I will do on Amazon or other French website then

Very good approach.

And I was also wondering about Amazon. How much money do you think we can SE them before they start to question and suspect us? (In total, not necessarily by region)

It's not so much about the amount of money made (SE'ers have generated tens of thousands of dollars), but rather how the methodologies are used with each and every SE, as well as the account's standing.
