Illustration needed for physiotherapy website

I need a illustration (hand drawed) for on my website in physiotherapy. If u look on the website (www.boostfysiotherapie.nl) you will see that there is a background with grass and someone running. I would like to change that in a cartoon-like picture that contain the theme psychiotherapy (maybe sport/moving, or massage) and also a connection with my company name (BOOST fysiotherapie). I am specialized in head/neck/jaw psychiotherapy so maybe it's nice that you can see that coming back in the illustration.

I'm looking for someone who can draw a picture with everything in it, the picture tells a story short of, so not only one character, more like what you see in nice graphic books with alot of colors (not only black and white)
