Simple cartoon style images needed for educational work

I would like some simple cartoons that I can use on educational worksheets. I need them in B&W and colour so that I can change colours if needed.

My sketching skills are not up to drawing these myself, so I'm hoping that you will be able to use your creativity here! Please attach a sample of 2 or 3 images to your bid, so I can be sure you understand what I need.

There will be more work to follow later once I have found the right person for the job. I will retain all copyright to the images.

I have attached some images I currently use to give you an idea of the style I'm after. They are going to be used for the 6-11 year old age group. I've also attached the list of pictures I need done.
