Hi
I understood what is your need. It's a little tricky, but I have some question in my mind. We can discuss on chat.
I am a 3D generalist, I have a good experience in modelling (organic and non organic), animation, rigging, effects, and post.
You need good quality for that so you have to choose a good freelancer for that.
For the demo I need 2 days to show you look and feel of final output.
I am new on this site, that's why the review of my profile is low, but you can trust me and check my profile.
I Am inviting you to discuss further details.
