architectural and structural drawings for an underground planetarium

most of the project is done but some elements are messing and i want a skilled rivet user to draw them so i can proceed in the same file. allready adjusted the elements that should be drawn in the picture below: + ill pay extra 100$ for someone who draw the structure of the building.. the building is conceptual, its only required to represent the structure not drawing them in precise or accuracy. it is an easy building and does not requires a lot of time for a skilled use
