Finally after what felt like much much too long I got myself a price sheet quickly whipped up in time for FWA. So now I have something that's a good starting point that isn't drastically undercharging myself either.
When I have the time and come up with a better layout I'll probably post a revised version and send this to scraps or something later. I don't really know yet, just decided to go ahead and finally post this FWA intended price sheet so future commissioners will finally have a nice starting point to figure what their commission might cost up front.
