Before you can start selling on Ebay you need to set up both an Ebay and PayPal account. Now, PayPal has very good step by step instructions in their customer support section. But please note you may see the option for creating a Primier Account but when you actually go in to set up the account the only options you will see are Personal and Business.
I strongly suggest that you set up a business account. Please click on this link to walk through the steps of setting up your PayPal account.
I have also included a video for your to watch on setting up a PayPal account. Once again, there is reference to a Primer account but that option no longer exists.
