15 Perron Brisbane based company, who service clients australia wide, I will get one of my drafting managers to go over your project ensuring we look in bcas and australian standards. Don't try and get a cut price offshore quote on this or you won't get your project through. After we do the initial critique, we can Aldo quote you to further alter the drawings and provide 3ds etc if necessary, I presume a planning permit has been issued for this project?
