Complete mechanical study of an object

Hello I've a work to make about this object (attached), it's an oscillator, modelised on Solidworks. It's an oscillator of a launcher of ping-pong balls. It's a small and easy job. What I'll need from you : - Kinematic Study - study of the amplitude of the oscillator - animation presenting the model - animation presenting the kinematic study, the study of the amplitude of the oscillator - I'm searching for serious provider, please begin your post by "FL. " if you are. - It's not all the work done, I'll give you another job on this subject (assembling, animation, etc), knowledge in CosmosMotion needed, etc. Budget is 30$ fixed cost.
