3 cartoon images for website - repost

I am looking for 3 coloured images (blue, the main colour) that will replace the 3 blue images under the heading "what happens after registration" and they should blend with the rest of the website as shown in the attached image. The three images should illustrate: 1. A happy person signing a form at a desk 2. A happy person completing an online assessment 3. An illustration of different learning styles ( could be someone making something, someone in a classroom, or a brain with three learning styles, auditory, visual and tactile) All graphics should represent business people ( the site is focused on sales training for professional business people) and all images should blend together in style and match the site colours. We will require an idea of the style that you will use so a sample image would be required prior to selecting the winning bidder.
