Hi, how are you? We are definitely fast and very neat AutoCAD users, but let us see your drawings first. Then I can tell you precisely is it possible withing 5-6 hours or not. We are team of only regular degree and master degree architects and great, very experienced designers with experiences in practice since 2006. I invite you to have a chat with me to discuss your project (if i work at the moment please have patience, will be with you soon). Best regards! Boris from Novi Sad
