Concept designs for interior designer

Hi
I am an interior designer with limited Auto cad capability and no Sketch up capability.
I am looking for someone who can transform my ideas on paper into a design document for my clients, I am looking for illustrated elevations and colour rendered elevations to give the clients a clear idea of how the room would look.
I do not like photo realistic images but prefer more free hand drawings.
I have attached the sort of thing I am looking for
a) room elevations of principal walls within the room
b) more detailed elevation including suggested colours and fabric.
The attached is an example of what I would need for each room.

I run several projects at any one time and if we worked well together I am looking for someone that can do regular work for me.
