Scam. A storyboard from an independent artist is only worth 5 dollars tops. That includes color, pen and ink.
MOST people, the majority who cant afford being ripped off or who dont have top notch corporate credit scores to take out movie production loans they cant pay back, are not looking for union artists who charge an arm, leg, and second mortgage for a few lines and some color on a few pages.
You're best off finding freelance artists on fiverr.com or a wholesale website. Some of the scammers on Jorgen's List wish they'd worked on movies and television but falsely state it on their resume's, b/c a few other artists did, too.
For that matter you can use Photoshop CS2 and Microsoft Paint the same as those hack artists do, and get your storyboards for free, minus a one day learning curve.
