Graphic Artist

I need a graphic artist. Adobe Illustrator to create some print documents. Your attention to detail is most important. We have a Roland SP-300V Solvent printer. We can print 700mm wide. The first job is a floor print as per the attached picture. The squares need to be 150mm. This will be 3 stripes to make the whole print. Once we have this first one correct. We will want to duplicate with different pattens.
