Create "Guides" for Our Game - 2D Personage Illustrations 2

I am looking for a talented digital artist who can create drawings of four people to act as "guides" for the NextYou personal development software. The guides will provide help on the use of the software (e.g. the illustration along with a pop-up speech balloon). Because the software has both physical fitness and mindfulness aspects, I am looking for both male and female characters with both fitness and spirituality reflected in the drawing. To work best with a diverse community of users, I am in particular looking for an illustration of a white female and a black male drawn as fitness coaches and an Asian male and Hispanic female to act as spiritual/stress management coaches. The drawings should be detailed, fanciful and very attractive but not overtly sexual.
