Hi
I understood what is your need.
I am a 3D generalist, I have a good experience in modelling (organic and non organic), animation, rigging, effects, and post.
(I don't have a knowledge of programming)
You need good quality for that so you have to choose a good freelancer for that.
For the demo I need 10 to 20 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.
