Here is the basic Siddur in English posted for you to download so that you can have one until you buy the complete Siddur. This is a very simple one but it contains the whole Amidah prayers and afternoon prayers. I want for all of you to continue to learn how approach YHVH our King.
p.s. If you are interested in purchasing a Siddur the best source is http://www.artscroll.com
