You may have gone about as far as you can with a keyboard and a camera and need a set of experienced eyes on site. Here's something you might want to consider at this point. Where I live, you can call for a inspection and even though you're not truely ready for an inspection, you can go over what you're about to do with the AHJ. If he or she sees something they don't like or that you've flat out got wrong, they'll point it out to you so that when you call for a re-inspection it'll be right. The charge for a re-inspection here is nominal - $30.
