KD on 3D models

Good evening, I need to make working design documentation with 3D models SolidWorks 13, in the models the entire composition, materials, etc., there are templates for welding, spices, TT, tolerances and examples of drawings design. The amount of work you determine yourself, how much you will do - so much volume and ladies. Term 3-4 months. Drawings are mainly metal structures, platforms, ladders and etc.
I am interested in the price of such work for 1 conditional sheet of A1 format.
