Site Plan with proposed dwelling drawings incorporated

I require an A3 cad drawing of a site plan for a small olive tree propagation enterprise, containing a dwelling, carport, water tanks, associated shedding and growing out area. The plan will need to show the site and proposed buildings etc, and also show a floor and elevation drawing of the proposed dwelling. I have sketched the proposed site plan and have the floor and front elevation for the winning bidder to use. I need this plan to scale, and labelled accordingly.
