I am looking for granite for my own business, I think it is good if I can start by 1 20' container for the 1st order, 500 to 600 sqm. right after that , if everything is fine, 1200 sqm order will be launched -Thickness 16-20 mm -Size: usable size on each slab from 600*800mm to 800*1100mm. The bigger the better but no need bigger than 800x1100mm. -No need 100% real natural black, can be dyed to make darker. - The cheaper the better. - Quantity : 1000 Square Meter - Annual quantity is 6000-8000 sqm - Line or small failure in a low proportion are acceptable - My finished product mainly is from 20x30cm to 30x40cm ( 90%). I can avoid the lines and spots if it is not too much and doesn't happen to every slabs and have much better price. I mean I can accept lose 5 to 13% of total area if we can have good price
