Simpel cat icons for cat book

Hi, I'm writing a book about cat behaviour and I'd like to work together with a creative spirit who can draw simple graphics to illustrate what I'm writing about. Most graphics will involve a cat, cat features, body parts or parts of the environment that it needs (litter trays, toys, furniture etc). I'm looking for someone who can give me a transparant price setting so I know what I will be paying for it. Ofcourse credits will be made once the book comes out. Prices here are PER DRAWING The time setting is quite urgent, I need someone to work with me in august 2017. Please send me a few of your cat ideas, so I can see if that is the style I'm looking for. I'm looking for very simple, plain lines (that we can change colours), but cute, not too cute, and something that doesn't already exist or looks like Simon's cat, the Aristocats, hello kitty, etc. It should be a adobe file, that we can change in photoshop or illustrator. If this book hits off, I'll be working on a second one. The files need to be unique for this assignment and not used anywhere else, I expect all rights to be transferred to my company.
