SMS Portal or Clone

if you check out [login to view URL] i want to clone the whole feature. you can create an account and login to access all they have. you might not need to make user select country whenever they are sending sms so that they can send to any country. i will be linking the gateway to a company in india and so i need a portal design to manage users and the likes, just like mcastmessaging.com. That simple who's up for this and i will prefer someone who has done this before with proofs. i am good at this, being a web programmer but right now i have a lot in my hands and its best i just sub-contract some of them to keep my clients.
