Im looking through other peoples price and times and this is completely unrealistic.
Really, it all depends on how much animation you wanted. If we are talking about making the powerpoint in Articulate Storyline fpr examplr, to make basic animation similar to powerpoint but with some interactiveness to it then it wont take long, maybe give me 2 days.
If you are wanting 30 minutes of 2d animation at a good quality it is much more than this, maybe looking around $2500+ for good quality.
Would love to help out and do this, however more instructions on the level of quality you would like.
Thanks for the consideration.
