Pigment Inkjet Ink for Epson R1800 Wanted

Want to buy pigment inkjet ink for Epson R1800 printers.  Will buy minimum 5kg per color per order but will first need small sample of each color for evaluation and testing before placing our first larger order.  This is an ongoing consumable for our company.  Once we find an excellent ink and reliable supplier, we will continue to re-order these inks as needed.

We need total delivered cost for samples.  Also need a separate, total delivered cost for a total of 35 kg of ink (only 7 colors x 5kg each) because we won't need any Gloss Optimizer in our first order.  The least expensive method of delivery is preferred in both cases (sample and larger order).

Thank you !
