Concept drawings

Hi - I am looking to get 3 drawings of some TV style set up so I can show people what i am thinking! One is of a simple studio setup up - So showing 3 people standing in front of 3 monitors, showing some cameras and lights in the picture - second is of a typical off tube commentary area with 2 people sitting watching various monitors and the last is of a tech area with people sitting at desks operating various pieces of kit - I may need a wide version of this and a close up version. I can do simple (Bad) drawings of mine to get across my thoughts to the person doing this
