Create a Figure for an Academic Paper

I am looking for a freelancer who can create an illustration for my academic paper. Attached I am posting how the picture should look like. I am look for a more professional version of that. The picture should be simple and should not have many details. The figure should highlight different types of firms in the winner group and different types of firms in the loser group. But, one firm in each group have similar pattern. Instead of colors, you should use some different type of pattern for the firms and keep the figure black and white.

If you have the necessary skills and experience, please provide examples of your previous work in creating illustrations for academic papers or similar projects.
