Sign-up form for an existing text messaging & sms website

Hello, I'm looking for someone to develop a registration form for a text messaging website. I've already a working text messaging website but currently the website is open for all (i.e there is no registration). My website allows users to send free sms to Pakistan and I'm using GSM Modem and Headwind GSM Driver ([login to view URL]) for this purpose. What I'm currently looking is: 1: A user sign-ups by providing his name, email and mobile number. 2: A confirmation code is sent to user mobile phone (using my existing system - GSM Modem and Headwind Modem Driver) 3: Once user has provided the confirmation code, He is now able to send text messages using the website by signing in using his mobile number and password. 4: The sent messages are being sent now by my existing system which was previously open for all. 5: GSM Modem and Headwind GSM Driver also support receving sms mode is call handler, and there code file available on the website, only need to setup. 6: Send forward button below every sms, when any user hit the button sms automatically go in send sms frame. There should be a small admin panel to look and search for messages sent by users (Search by text message, search by sender mobile number, search by receiver mobile number, search by sender IP) or block any users or blacklist any words to sent through text messaging service. Any ambiguity can be discussed via Live chat.
