Which paypal account should I use?

Hi there, I’ve found out that there are few types of paypal account, including personal, premier and business. So, which one can I use for s2member? I intend to open a website to sell a service and perhaps some products online, but not under a name of company, but I do it personally. I’ve gone through s2member website and they stated that we need at least a business account. However, according to paypal.com, business account is for merchants who use a company or group name. So, I think perhaps premier account is more suitable for me since it’s for individual who buys and sells online. But, I’m not very sure whether it could meet the minimum requirement of s2member…. somebody please help me!
