It's a relatively easy fix at home if you've got a hammer and some punches, maybe even a drill and drill bits. Knock out the pins, use a hammer to adjust the gas block until its straight, then redrill and reinsert the pins. Then take it to the range and make sure its still got enough gas to cycle. Usually they do if the adjustment is minor.
This is a pretty common fix for an AK, and is covered in detail with a
brief google search.
The AR15.com AK
Build it Yourself forum should be able to help you out if you want to take on the project yourself.
If you're not interested in doing it yourself, any local gunsmith worth their salt will be able to do it. A fix like this should take less than an hour if they have the right tools and experience with AK's. I'd try calling someone locally and getting an estimate, they might be able to do it in the shop while you wait.
Hope that helps.
