T-Shirt design, production and shipping

We need T-Shirts with Company Logo. Preferably the logo should be screen printed to 100% cotton shirts. The shirts should be of good quality, around 220g/m², normal fit. The project can be put into three steps (1) Simple design: All there has to be is the badge with the stylized "S" inside de hexagon on the front and the logo saying "Steiner Heizung-Sanitär" on the back (2) Production of around 100 shirts in two color ways. One batch of shirts should be heather grey with blue/black print, the other batch black shirts with silver print (3) Shipment to Austria, europe I have added the logo data, and a sketch of what i imagine for the shirts to look like Please note: We have an existing logo, that will be used, this is no search for a new logo! for any questions, please do not hesitate to ask.
