With a little bit of brain power, I'm sure anyone could handle a permissions system, maybe even you!
if you're going to set up a long term system for permissions, especially if you are running multiple worlds, I suggest bPermissions. It is perfect for multiworld enviornments, infact I use it on my server to keep the permission configurations between my creative amd survival worlds seperate, as well as configure groups just the way I want them (per world ofcourse)
Also, if you're looking for some help, I suggest visiting their IRC chat channel. I think it is #bananacode. They can give you some useful tips regarding a lot of different topics.
I hope some of this helps, and remember when coding permissions: YAML aint markup language.
