landscape design

I am looking to hire a landscape design expert to help with my project. This project is for a medium sized area, approximately 1000 sq ft. The desired style for the design is modern, however I have a few ideas of plants/features that I would like to include in the project. Therefore, I am looking for someone who can incorporate my ideas and also bring their expertise to the project. The ideal candidate should be knowledgeable in landscape design and understand how to execute a modern style. I expect an experienced and professional approach, and the successful completion of the project in a timely manner.
