Need more and specific details.
How much it would cost to purchase the membership?
Is it possible to use Paypal or other payment method like moneybookers, bank or you need to pay using only with credit/debit card?
What will an user get after purchasing the membership i.e. benefits and reason for joining?
What type of resources you will provide to start a campaign?
Most of all I need to check the entire process and the validity of the purchase.
Please, contact if you feel interested and my bid is a random one. I will post a revised bid after having complete details.
