I need drawings to illustrate how a shop will be fitted out

This will involved CAD drawings with floor plans of a deli shop front area and rear kitchen area illustrating the fixtures and fittings. In addition to the floor plan, I need a 3D impression of both rooms. I can supply my own rough floor plan in a powerpoint slide but you would have to use a bit of imagination to show the 3D fixtures ie the shop counters and hot and cold display units. I can provide a rough estimate of sizes of display units that I want. I do have have reasonably accurate measurements for the length, width and height of the rooms.
