Hello, I am new to Freelancer, but I have been a designer for 30+ years. Your project sounds interesting and fun... I'd love to discuss it further with you. (BTW, I am just south of you in Carlsbad, CA.) The other project I have competed on Freelancer was for an "extreme sports" photographer who wanted something somewhat similar to what you are asking. Please check out his review of my work.
A little more about me: I am an illustrator/designer and a nationally syndicated cartoonist. My clients include DC Comics, Warner Bros, Hallmark, Cartoon Network, Hasbro, CBS, Showtime, BMW, The Nerdist, Whataburger, Chick-fil-A, Arby’s, Olive Garden and many more. My work has appeared in a New York Times bestseller, ComicBook Men (AMC), @Midnight (Comedy Central) and The Tonight Show (NBC). I've also been a panelist at San Diego Comic-Con and Wondercon.
Please check out my abbreviated portfolio for a small sample of what I could do for you. My daughter, 7, is just getting into skateboarding, so she would be stoked if I got this project. ;-)
All the best,
