Caricatures of famous investors required for a website

Caricatures required for 37 famous investors for use on a revolutionary new website "Stockviews.com". Aim for caricatures is to have a clean and stylized look with a "graphic novel" feel. These investors are all leaders in their field and inspire others to invest in a sensible and long-term fashion - I want the feel and the look of the icons to inspire users in the same way. An example of how the caricature will appear is shown and the caricature will also appear as an icon elsewhere on the site. The example given is probably too detailed for my requirements however and a head and shoulder shot only/ something more stylized would be more appropriate. Please submit 1-2 examplesvof your work with your submission that most closely illustrate what I am looking for. If you wish you may also provide an example of how you would do Warren Buffet for the purposes of this site. Cost is a factor so please keep the icons relatively simple and let me know a price per caricature (Total compensation will then be that price x 37)
