26964 Web 2 SMS script.

Hi, I would like a script that can send Free Sms's to Any Australian Mobile (Telstra, Optus, Vodafone, ect) I know this is a simple script and I would like the developer to embed it into a basic html page, and configure it to my server. I would also like a document that explains the principles of how it works, plenty of comments in the code to explain each section. No transaction fees should be received from this process, neither myself for sending the sms's and nor the recipient for receiving the sms. It needs to be 100% free from charges. Hence the reason I want to understand the process of how it is done. Privacy is appreciated so please don't have the sms's forwarded to any other server. PS: If you can have the mobile reply an sms to the server and be displayed on the .php that would be fantastic! But this is not needed in order for you to bid on this project. Regards, Jared
