Big shoe co is the way to go if you can get your foot in the door. I wouldn't even bother with hard good companies. It's obvious upper management and their owners pocket the majority of profits while screaming "core".
Even go after your shop owners, if they are successful and you do media for them don't do that shit for free.
When you ask and they don't say no you know your worth.
The core industry has made itself look bigger than it actually is. It's a complete joke. Squeeze everything you can from anyone you can if they intend to profit from your work in anyway.
