I need an office design render (3d)

Hi,

I'm working on a project and have the design in the paper, but would like to have it rendered to show exactly how the project is going to be.

I have the the AutoCAD file and the plans in 2d paper with explanation of each office plan.

I need the work ASAP.

Please before proposing send me your previous render works, and the time needed to finish a two story building rendering (interior only).

Thanks and regards,
Abdullah
