Merino yarn for knitting

Hello,
I'm looking for Thick & Thin 100 % merino yarn (for knitting), in skeins of 100 gr.
I would like to consider importing this yarn to Israel.
I'd like to know weather i can ask for a custom order of colors, what is the minimum quantity per order, if you ship to Israel and costs.
Looking forward to hear from you.
Best regards, Shira
