Do some 3D Modelling

Attached there is a character that i need to be modified slightly. slightly to make it unique from its current form. I would also like to have extra animation features added. i would like the following animation features: slide forward(see slide left and right animation) punch left, punch right push forward(with two hands) command sky with two arms whip(this animation will only be executed once the ingame character picks up the whip so transition needs to go from running with no whip to running with whip. this will need to be imported into my unity project and animations accessibly via animation controller. Successful complete will grant more work
