Find a creative Landscape Architect or Designer that you could hire for a concept drawing. If you are going to need to have someone to acturally do some of the Hardscape and Softscape a company that is a Landscape Design/Build firm might be the way to go, which will reduce or perhaps eliminate Architectural consulting fees.
I have owned my Design Build firm for 30+ years, find someone you are comfortable working with, they will save you time and money in the long run, and you will end up with a yard that works.
