Animated video presentation

I have a few presentations that I have made of one of my companies and its products. I have defined a few concepts that I would like to make into an animated video to incorporate into my presentations when I meed investors, customers or potential employees. I have defined a few cases for each stakeholder since the selling point is of course different depending on the stakeholder. I would like to create roughly 5 - 6 videos of 2 - 3 minutes each and the speaker voice will be recorded and added separately so I need someone who can take my illustration and description of the case and make a nice and professional animated video.
