EST is the main active timezone as far as I can tell, so you're all good there. (I'm BST. Sobs. So many 2am events.)
Good-aligned FC's are the most common type, though far from the only type. I'm not involved in the crime RP side of things at the moment (my character is, roughly/practically speaking, in law enforcement), so I can't comment on the exact level of incidence, but I know they exist. On the Lawful Evil side I've seen smuggling syndicate FC's, shady merchant FC's, Garlean FC's; on the more Chaotic Evil side of things I've seen "evil scientist" FC's, voidsent-ally FC's, and linkshells for broadly-speaking "villains". Even if the FC you find first of all isn't exactly what you're looking for, people are generally pretty good at putting you in touch with other people that might be.
The linkshell hall and the free company hall can probably help you find half a dozen, especially on the good-aligned axis, at least one of which is bound to suit your desires. Don't be afraid to join linkshells as well - they're good for making connections, and connections can lead to you finding The One True FC more reliably, since the ones suggested to you will be vouched for by something other than their own recruitment messages.
