interior floorplan

I have a 2 port garage that I'm looking to covert into a game room. I'm looking to get a floor plan made. I have sketched the room by hand. I took measurements that may need some slight adjusting, but they are pretty accurate. To be included in the 3D model, I need an image created for gaming machines, based on the artwork and dimensions I have. I want to use the game cabinet image to figure out how I want to lay out the machines on the floor. I hope that makes sense. If this is something you can do, I will send over what I have. Also discuss the cost of this project, based on my needs.
