Hi there,
I have studied your project that you need artwork of race cars going round a track so on . You will get customised original artwork tailored to your own specifications and corrections for free . I have worked on similar projects to what you are looking for.
Check my portfolio to see my previous works:

You will own 100 % copyright of the design along with source files.
I can start immediately.
Thanks and Regards,
Suparna
