Free SMS script -- 2

I'll explain in detail what must be done . I have a site in WP [login to view URL] and on this site I have to enter a script (such as wp plugin or page ) that allows you to send SMS from your website to any mobile phone or smartphone using this site [login to view URL] sms / but with a mask on my site . Visitors to my site ( without registration ) enter data in each field ( including verification code ) and then pressing the send SMS message arrives in real time to the recipient's mobile phone or smartphone . SMS can be sent anywhere in the world. Then they must add social share buttons AddThis type . As for the payments I can pay only when you finish the job and show me that the script works . The feedback I leave only work concluded . You can do this for me ? You can guarantee these results ? I await your response urgently Thank you for taking the time to read me my request
