Creation of Animated Characters (Dog & Cat)

Hello, we are a company of pet food, and we need to create 2 mascots (cat and dog) for our brand. Therefore, we're looking for skilled designers/illustrators/cartoonist with experience in the major advertising agencies, who can: Create and develop 2 funny creatures, a dog and a cat in all kinds of positions and adapt to several themes like, Xmas, Easter, Summer (beach, soccer), Winter, Spring, Autumn and hurt (broken arm..) These mascots must be able to adapt to a site and to widgets. Besides the above, we also need: 12 small cartoon boards with copywriting. The common point of the story will be the funny conflicts between cats and dogs (ex: Tom & Jerry), but adapting to a message like vacations, Xmas, etc (to be defined) And finally, we're gonna need a fridge magnet and a sticker with these mascots. Thanks
