animal logo illustration

I am looking for a freelancer who can create a unique animal logo illustration for me. We need to show 3 mammals, a dolphin, a harvest mouse and one other medium sized uk land mammal. I am looking for a line drawing style, one that is simple but detailed enough to convey the essence of the chosen animal. Please see attached [pdf which the client likes as a style. I need 2-3 variations of the logo illustration created. The right freelancer should have great attention to detail and have experience doing similar tasks. The chosen drawing may need a few amend stages as well. We need the final logo supplied as a vector file and the client owns the total usage of the drawing.
