WorldGuard is not that hard to use at all. I understand that plugins are confusing when you're first starting out. You will get the hang of it though if you just stick with it. There are plenty of articles and YouTube videos already out there on this topic, all for the magical price of FREE! Paying someone to help with something as simple as WorldGuard is not worth it. Also, if you never learn to do these things yourself now you will be faced with more and more problems down the road.
