Create Promotional Videos

Looking for someone to create short 1-2 minute promotional videos. These videos should be animated videos (cartoon/whiteboard videos). I am looking for 5 videos in different topics (you'll be given the topics). Each video must be in different style and graphics. I'll provide some script ideas. You need to come up with the actual script. Budget for 5 videos is around $50.00 in total and this is a long term project. We need more videos next month. Go ahead and bid $50 or below if you wish. Also include in your bid : 1. Turnaround time for 5 videos 2. Sample of previously done videos 3. Similar projects done before Thanks.
