Hi there,
Let me know what would be the first animation you need me to do, and I can update my bid with a more accurate quote. I would prefer we do the animations one by one, each in it's own project/milestone.
I am fluent in JavaScript and good with 3D modelling. Did 3D animations as parts of web apps before, so I'd be happy to work with you, and I am sure you'd be happy with the outcome.
Regards,
Julijan
