AutoCAD Macro Ceiling Plan Required in 2D

Hi You need to have experience with creating macros to produce simple 2d drawings in AutoCAD to be eligible for this project. I am looking for someone to create a macro based ceiling plan in 2D. This will be made up with series of rectangles and circles controlled by a user interface. The user enters simple parameters and the plan changes shape. I can provide a drawing to show you what is required but I am testing the water to see if I can get some $30 bids. Once I have viewed some profiles I will make contact and provide a drawing of what is required and adjust the bids if necessary. This is a prototype and I will show it to my boss, if it is successful then we can do more. I look forward to seeing some profiles, sorry I cant provide more information this only just occurred to me.
