debian cellphone sending sms text messeging via php

I wish to send out sms text messeges via a cellphone connected to a debian server. I wish to send these messeges out via php scripts. Can anyone help? 1. I need the cellphone connected --you tell me which one (US carrier of course). 2. the sms texting product - hopefully open source, but interested in all. 3. Need the cheapest method of sending and recieving sms text messeges. (sending sms text through email will not work for me ). thanks mjh ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
