Cartoon Illustrations

We need a cartoonist/ graphic artist/ illustrator to take the fish in our existing logo and 'animate' the fish to become a 'character'. We would like 5 coloured cartoon-like illustrator of the fish character in various poses (and possibly with items like a notebook or camera). I have attached drawings of a wooly mammoth elephant which is similar to what we are after with the fish. We like the 'vector' look of illustrations. We would like the fish to be happy looking and cheerful. We would also request upon completion the source files. Please include relevant experience, link to online portfolio if you have one or to examples of your work.
