Media Wall Joinery Drawings

We are looking for a designer to produce scale CAD drawings for a media wall we are looking to have built. These need to be detailed enough for a joinery company to build from but also have some CGI version for us to visualize the space.

I have attached a sketch of how we think it would look but would want to tweak the spacing and size of units. I have also attached some mood images of the look we are replicating. Finally I have attached an image of the wall it will get built against.

Please provide quotes, experience and how quickly you can work on this?
