Professional Illustrator Required To Be On Call

I need an Illustrator who can illustrate images in a similar style to what I have attached, usually sketchy or cartoon style. You will need to provide these images on a fast turnaround when I make a request.

An Illustrated Image for 1 person is £12 and 2 people will be £18. This will be a regular job and you will need to be on call to start jobs as soon as a request is made to you. You could earn up to £300 a month.

Please provide links to your work.
