Hey Jim,
I would be the right man for the job. I have worked a lot in this type of graphical illustrative style. (Caricatures, illustrations for books, web, comics etc.) And I'm willing to offer it to you with the best relation of quality, quantity, value and time. I'll do what you want and I will give it to you with the best reasonable prize!
For you to know what you would actually get from me you can have a look over the sample image I specially drew for you based on the tennis player. It's displayed in my portfolio gallery and also on the following link: [login to view URL] .It's a personal representation of the image quickly sketched. Adjustments regarding the project can be made - line weight, detail, color etc. I can even draw 100% using the provided style. You just name it!
On the sketch I tried to improve the original artwork by adjusting the line weight a bit.
To get familiar with other work I have done, you can check my portfolio at: [login to view URL]
Hope to hear back from you, Jim. And hopefully I can help you out with this project.
Take care,
Martin
