Simulate a Frog jump in Unity3d

Please watch the video below

I’m looking for a developer, experienced in Unity and especially physics and joints to simulate the Frog Jump for me, it should be realistic and Physics based; that is use the force and proper motion to create the jump. you are free to use a 3d model of your choice as long as it employees proper joints.

please beware! this should not be done with animation; that is to animate the from jump and then apply force, rather the force of the jump should be translated to the joints. more details on messeges

and by end of the project, I would need an explanation of the program and how it functions.
