We need an online epayment system. Similar to a system that is PAYPAL. We want to create a virtual currency company for the following
1) End Customer (To buy from merchants / To inter transfer money / To withdraw payments)
2) Merchants (To sell their products using our API (As PAYPAL/Moneybookers/alertpay do) / To inter transfer money / To withdraw payments)
and maybe some more standard features will be added as per PAYPAL/Moneybookers/alertpay have in them currently.
Users will be able to deposit money through all current gateways on the internet.
You can use open source system such as JOOMLA (CMS)
But we believe you have to develop a custom module for the epay system. Only you have the expertise then jump into JOOMLA. Other wise develop a custom system as described before.
