It might seem a bit challenging and bit intimidating for the first timer.
If you have help, someone with knowledge of what they are doing, you might consider doing it yourself.
But if you have any reservations at all about your abilities to properly set and inspect your rig, get a professional. Next season you'll be the expert and I'm sure you will be doing the tuning yourself. But the first time........ you may want to solicit an expert's services.
