Creative Artist To Imitate An Art Style

Please look at the attached artwork by Ken Done. I am looking for someone who can imitate that style of simple, bold and colorful design, and apply it to artwork we need done for our tour company. We operate tours to some of the USA's national parks, and the idea is that we will take the best known elements and features of a park, and create appropriate designs for a logo, T-shirts, etc. Please send appropriate samples of your work. In order that I know you have actually read my proposal, and are not using an auto reply app, please quote the word "geyser" in your reply.Thanks.
