Basement layout services

I'm looking for a professional to help me design the basement layout in my home. The primary purpose of the layout is to make use of the space as living space - it will not be used for general storage purposes. Specifically, I need help determining how to organize the space in order to accommodate different types of items (such as an office area, an entertainment area, and so on). I would like to create at least 4-6 distinct rooms or areas in the basement layout. Thanks in advance for any help you can provide!
