WordPress is a nonprofit open source blogging platform, which means that absolutely no one is paid to offer support (unless you actually hire a contractor, of course), so all help is offered through the Support Forums by volunteers and all documentation is provided through the Codex by volunteers.
If you know what you’re doing, why not stop by to help out a bit? In fact, even if you’re just starting with WordPress, I bet there are a few folks that you could help. After all, that’s how I got my start.
Helping out is easy to do, and there are some handy guides for new Support Forum volunteers and new Codex editors. Don’t worry about getting your answer wrong the first couple of times, someone will correct you and help you out, it’s all part of learning. In fact, helping someone else is often the best way to learn yourself.
