AutoCad Home Remodel

I am remodeling a home and need a designer to create an aesthetically pleasing design. Attached is a photo of the current home in midst of the remodel. The roof height on the left is 8 ft and 10 ft on the right side. I want to add a gable on the left to add space and light to the room in the attic area. I want a grand entry in the center. The height of the roof can be increased so that the home is not so flat. A higher roof only on the right side is preferred. I can provide AutoCad drawings but these drawings do not reflect the current roof changes. I'm hoping that the freelancer can propose a roof redesign.
