Having finished an online photography course, I may need to upgrade from my combination of iPhone X / GoPro Hero7 Black for landscape photography.

I'm trying to monetize my Instagram, via good content and automation - free hotel stays while on the road mainly.

Ideally I want to test a range of cameras in a landscape setting, get all of the images on a file and compare the quality to figure out the optimal level of quality against funds invested.
I may attend a photography club and ask people with the same shot on the same day to send me the file - do you guys have a better method to figure out the optimal level of camera to buy?

Also, is Amazon the cheapest place you guys recommend to buy a camera or am I missing a trick?

FWIW, I'm looking at getting a full sensor mirrorless camera - Sony A7R would be bottom of the range here.
