Screen Printing Forum

I'm going to try screen printing for personal purpose. I have contacted a local screen printing shop, and I got some prices. But the sell their Ink in gallons, 3 liters. I suppose I don't need 3 liters of all the colors at the beginning, and I don't have the money to buy the necessary colors to start. It is Rutland plastisol ink. Is that a good-quality ink? If there are any Norwegians here, or Swedes, could you please help me get hold of some smaller amounts of textile paint in all the necessary colors?
Thank you in advance.
