If you can astral project you're perfect for this jobs! All you have to do is two things: First, you have to astral project to a place then when you're done mention everything what you saw; then second, astral project back to the place and do some clearing (More on that mentioned later). The best bid wins!
I have naturally been able to astral project for the most part of my life. I usually am able to successfully travel about 3-5 times a week ... This project sounds like fun, i can't wait to try it.
