Want a subscription based SMS website where a user can 1) register to become a member i.e gets a user & password & 4digit pin number 2) On becoming a member, the user then loads credit to his account via paypal or thru our merchant account and credit works like this;- 10 credits for $10, 20 for $20, 50 credits for $50 etc. The user can now send one or more SMS to one or more phone numbers/email based on if he has sufficient credit, 1 credit for sms message and 1/2 for email. An Administer function should allow the adminstrator to change the number of credit allocated for sms/email. Also the user should be able to review account history and topup credit. Any of the popular SMS gateways and SMPP for email should be used.
