My webcomic and posssiiiblyyy commissions...?

Hey guys! I first wanted to do a shameless self-plug for my webcomic, Knight & Day! You can find it here! I am on a three-week streak of updating it regularly on Mondays. C:
The comic focuses on an urban fantasy setting, with the fantastic is the normal everyday life. The "Knight & Day" is a service, much like a detective agency. There are three main pairs who work at the agency, and the first three chapters are focusing on the typical cases they work on. To start off are Mei and Meredith Liao, a married couple for the past 400-500 years. Mei is a knight dedicated to protecting those she loves, whereas Meredith is an arcane mage who believes anyone is worth saving. 
I saw several months ago when I mentioned working on a webcomic some of you guys were interested, so there you go! ^^

You may have noticed the second part of the title: commissions. I have a solid idea of what kind of I'll do/accept and even have a graphic almost complete to post. The main thing holding me back is figuring out PayPal. I have an account, but I'm not sure if it's right? Like I thiiiiink I have to have it as a business account but it's asking for "legal business name" and...what? I saw when I first started to try to set it up (before I saw the legal business name and fled to a regular account) there was a chat feature to help with the setup, but when I went to upgrade to a business account the chat feature wasn't there anymore???
If any one of you guys more familiar with taking commissions can help me out, I'd appreciate it!
