Free Credit SMS PORTAL

I NEED AN SMS SOLUTION THAT CAN BE LIKENED TO THE SERVICES OF [login to view URL], CELLEBRUM.COM. A GOOD DESIGN IN PHP IS NEEDED. MORE IMPORTANTLY, THERE WOULD BE NO NEED FOR ME TO BUY CREDITS OR WHATS EVER. I NEED IT ON MY OWN SMS GATEWAY INSTALLED ON MY SERVER. THERE WILL NO NEED TO INSTALL ANY CREDIT CARD BILLING CLIENT BECAUSE MY TARGET CLIENTS ARE THOSE WITHOUT CREDIT CARD ACCESS OR ONLINE BANK EITHER. I NEED A SOLUTION WHERE I CAN GENERATE CREDITS TO SELL TO MY CLIENTS MYSELF WITHOUT PAYING NOTHING TO ANYBODY THROUGH MY SMS GATEWAY. THESE CREDITS WOULD BE SOLD IN FORM OF RECHEARGE CARDS OTHERWISE KNOWN AS THE FELLAZ SMS RECHEARGE CARD. THIS CARD WOULD BE GENERATED IN THIS DIFERENT VALUES. ON ENTERING THE DIGITS ON THE RECHEARGE PAGE ON THE PORTAL, THE VALUE SHOULD BE AUTOMATICALLY ADDED TO THE CLIENTS HOME. BEAR IN MIND THAT THIS CREDITS WOULD BE SOLD IN THE STREETS NOT ONLINE. ABOVE ALL, IT SHOULD BE DELIVERED ON REAL TIME. PAYMENT TERMS AND MEANS ARE FURTHER NEGOTIABLE. GET BACK TO ME IF YOU CAN DELIVER THE ABOVE SPECIFICATIONS OR A BETTER WORTH.
