Three task on Unity with Leap motion (hands pinching, random, trandform)

Hi guys, I want to find a freelancer to teach me how to finish some task on the below when using Unity with Leap motion. I already created the hand menu and the leap motion controller. My budget is no more than USD400. If you inerested on it, discuss with me please. Thank you! Tasklist: 1. both hands pinching an object (cube, sphere, cone) after selected from the hand menu. Also, both hands have some tips to let the player know that they have to pinch their hands to get the object after selected. 2. The player's hand can take a cone, cube, or sphere randomly from a box. 3. An object can be transformed into another object when passing somewhere.
