Dear sirs, I am professional 2d animator, I can animate your promotional video, create the storyboard, and then even create the courses animations. My rate per animations are:
Rig animation (as most of explainer videos online): $13.5 uds per second of animation
2d classic animation (as cartoon shows, frame by frame): $29.5 usd per second of animation
Please take a look to my portfolio here on Freelancer, you will find many samples, but keep scrolling cause there is much more works there.
