Create an Unity animation from an existing project and add few features

Hello, I need a Unity animator/developer. I bought this asset: [login to view URL]!/content/24523 It includes several animations and I need a freelancer to edit a full animation (around 30 seconds with a camera fixed top view) using several of these animations included in the product. I will give a video to fit exactly the timing explaining which animations to use and at the good timing. Also, I need to use a background image (under the scorpion as a floor) that is a picture taken from the camera (using Unity code). User can enable/disable the camera flash by double-clicking on the screen. This background picture must receive the shadows of the scorpion. Last thing, in the code, I can set a variable from 1 to 70 and there is a rectangle in the animation that will load the associated texture depend on the variable ([login to view URL], [login to view URL], ..., [login to view URL]). The source code must be with Unity 5.3.5. Please contact me to talk about the project. Thanks.
