Not to piggy back on someone else's thread...but I've got tuning issues also.

I've had my bow for two years now and it has not been tuned or adjusted sinceI bought it. After adding and changing accessories, I am having trouble with the tuning and timing. I must admit that having only been involved with bowhunting a few years, I am not as knowledgeable as I would like yet. If I was to take my bow to the pro shop what would their tuning process involve? And ball park figure of what I should expect for acost? Thanks.
