Cartoon Truck

Hi I need this company truck (green and white truck) turned into a cartoon, except with a blue sky and green grass. The white truck I have attached is the style I want. This project is for a large vinyl that will go on the water tank of the company trucks. I will need all files upon completion.
This is a very important project and only want the best designer. I prefer someone thats fluent in English to make communication easier.

Thanks
