I don't or ever will charge for producing any analysis or report, but it does eat up a large portion of my free time, so if you enjoy my content, do consider throwing a few bob towards my extremely nerdy hobby, I would be very grateful! I do most of my work in coffee shops, it's something about the environment that makes me very productive, so if you sponsor me the price of a coffee, I can also take a request for a sheet or analysis! (I take requests anyway, but you'll feel extra special if you sponsor one!)
