I don't know of any FCs currently, but you may be a good fit for the Open RP Linkshell, which is focussed on helping people find RP.
Given time constraints, something like a FC plotline may be on the tougher side to keep going. I'd recommend trying to build up some contacts first, and then see how things go. I haven't seen any FCs that would kick someone for a couple days of inactivity, but if it's a regularly occurring thing that could last for weeks at a time, that would be a deterrent.
Another resource is Nefzen's calendar, which combines things found on the RPC and tumblr for a better calendar list of events and taverns. The agenda view is probably a little easier to sift through, but it helps give an idea of what's out there.
