I might be able to get some 1st, 2nd, 3rd grade books from our school if you are interested. I can also recommend some Greek-English service books that are somewhat inexpensive, I have a work in progress of the Divine Liturgy and Vespers in Greek-English (of course the selections from the Ochtoechos, Psalter, ect are not included).
At this point, anything you could recommend would be helpful. In particular, the grade-school books would be helpful. Could you see about how much such text(s) would cost, and from what address we would get them from? 
Nektarios,
We're trying to learn modern Greek at this point, after which I'd probably go on to Koine (if things went well). We were trying to do it as it seems most people learn their native tongue. We've begun by learning some of the words, doing the alphabet, etc., that we got from a travelers/tourist book in English/Greek. We figured that if we were at least somewhat familiar with some words and how the words were put together, so to speak, we'd be able to more easily learn syntax and whatnot. If you would also have particular texts to recommend, we're certainly all ears
George,
Thank you for the suggestions 
I will have to revisit this thread if/when I start on Koine.
