It is very strange, isn’t it? so many payment option compliant on the forum. if you want to do the business, you have to have tools in hands. It is simple way to receive payment. despite of USA or outside USA.
Register a cheap but legal foreign company, opena foreign bank account outside USA. register a foreign company moneybookers account, ecocard, neteller, or other e-payment solution. For moneybookers, just send to own USA moneybookers from foreign company moneybookers which collect money from casino affiliate. you can do the same with other e-payment solution as per moneybookers method if you like.
