The firewall won't bother you (assuming you wish to get around it); it's there for the masses.
Any idiot with a US citizenship can get a tourist visa, lasting a year and having only the requirement "visit Hong Kong (or any other non-China location) every three months" (I was unambitious, and got a two-month one). Someone of my acquaintance says he paid a visa-help company $1000 and got a business visa, good for a year and imposing no requirements.
I have, in the past, had a working visa; if that's what you want, it's generally done by your employer, not you.
Your "I love China" kind of leads me to believe you'd be familiar with this already... what kind of complications have you experienced?
