    You are bidding on designing 2 office layouts. I have one now and will give you another in 1 to 3 days. One of the first bidders will probably win the project since I need this done quickly.I need someone to design my office floor plan in AutoCAD or some design layout program. I need this done in 2 to 3 hours of accepting the bid. I have all measurements on my rough draft and may be off by a couple feet. I will be available until 12am EST tonight to answer any questions or tomorrow morning around 8am.I will need the original program files and the layout in PDF. I will need you to possibly make revisions to both layouts.Thanks,Matt
