SMS using Asterisk

Please read this WHOLE description before you bid... I already have Asterisk installed and configured. I need to send and receive SMS/ Text Messaging using the number that shows on my Asterisk set up. So when I send a SMS the recipient will see that number ONLY and will reply to that number ONLY. Everything MUST be managed from my iPhone. So when I send SMS, the recipient doesn't see my real iPhone number, he, or she sees the number on the server and they reply to that number, and I get the SMS on my iPhone. Possible to do? If yes, please PM me, I want to know how this can be done. If you the right person, you are hired. Thanks.
