Hey Muhammad, glad to have you on board. :)
We have two ways for you to get paid for your sold models:
1. PayPal
2. Skrill
After numerous issues regarding orders through Skrill, we decided to let buyers to pay only to PayPal account. In this case, we put our PayPal account to your payment details, we collect money and in the end of a month we send the money to your Skrill account.
We help buyers to purchase models without any problems and later just send the money to designers from our Skrill to their Skrill account. This works good so far.
Simply download seller agreement, sign in it and upload it back through your Account Settings.
Hope this looks more clear now.
Alex
