Hi! I am a storyboard artist, and illustrator for short explainer videos. Usually, the minimum cost for storyboard, which I think is what you want to have (as you said, the images should support a statement) and illustration is 300 USD per minute of animation. A minute consists of 12-16 frames/scenes. I am not allowed to bid lower than what you've put here as project budget but, I'd like to bid for 300 GBP for black & White line drawings of people. On my portfolio (https://www.freelancer.com/u/Shijou0821.html) you'll find character designs which I've used on the explainer videos I illustrated. The styles I used are preferences of the clients. You can choose a which style you want the illustrations to be. You can search on youtube and find a style of your choice. I am a very versatile artist. Or, I can make sample illustrations and you choose which style you like. I have no problem drawing people in different poses as the illustrations I am creating are in layers and Ready-For-Animation so these are made to make different movements. For further details, just send me a message here, we'll discuss them and I'll answer your questions. Thanks! Have a nice day. :)
