Hello! After checking the links I know exactly what you need. I´m placing my bid to offer a slightly different option that might work just fine for you. Please contact me via PM so I can send you a sample of the animation I can provide to you, very very similar to the links you provided.
I have over twelve years of experience in animation and video compositing.
Please check my portfolio and my REVIEWS from others employers; There you will see my level of expertise and skills. I´m looking forward to start with your project, I am a very serious person, hard worker and always willing to give the best out of me.
I hope we´ll work toghether,
Thank you!
Emiliano
