I would love to help! I'm a children's cartoonist and illustrator, with some samples of my work at http://www.catherineharrell.com. This project sounds wonderful, and I know I'd have a great time drawing that pirate character! I'll start by sending you some sketches, and you can pick the ones you like. My bid also includes revisions, so you can modify the drawings to fit what you had in mind.
Thank you, and I hope your daughter has a great birthday!
