Flash game (similar to Donkey Kong)

We require a flash game, similar to the of the old classic, Donkey Kong, with a couple of character changes. If you are not familiar with this game take a look here [login to view URL] Character changes are as follows Donkey Kong should be replaced with a mechanical crane gone wrong, The princess should be replaced with a switch, (turns the crane off when our hero reaches it) Mario (the hero) should be replaced with a character I will call "Rob the roughneck" To find out what a roughneck is look here [login to view URL] I would like the graphics to be a little more polished than that of the original game. Five levels should be enough! If you bid for this project please provide other examples of your work as part of the bid!
