You can buy the image from shutterstock.com and then use a vector drawing program, e.g. Inkscape, to trace the image. There is a tutorial on how to trace an image in Inkscape here. (You may want to try this out on a different image from e.g. Google Images before buying the picture).
As an example, I did it for this picture:

I've taken the following steps:
- Import the picture into Inkscape using File > Import
- Trace the image by selecting it and then using Path > Trace bitmap; use Color Quantization, with 2 colors (the 2 colors will be black and white)
- You now have two objects: the original bitmap and the traced vector version of it. Delete the bitmap by selecting it and pressing
Delete.
- Now save the file as a pdf file
Alternatively use inkscape2tikz to export to a TikZ file. This plugin has to be installed manually (see webpage for instructions, it's pretty easy). Here is the resulting TikZ code.
