Welcome to the board Koolrayz,
I agree with the others that your site looks promising.
The absolute best indicator would be to find healthy seng growing there already.
Next I would look for Maidenhair fern - in my opinion the best companion plant for seng.
Here is a pic of a bunch of maidenhair fern and if you look just up the hill to the left there are a couple of big old seng plants.
maidenhair fern will only grow where there is increased levels of calcium in the soil and that is something that ginseng needs to grow well and be healthy.
There are lots of other good companion plants, bainberry, cohosh, even mayapple (which should be coming up real soon - it is up here in Middle TN already).
Your site is quite different than mine in one way - here where I live we have all hills and hollows, where your site looks to be quite flat.
Ginseng is succeptable to root rot and if you plant in the low areas where the rain water does not drain off well, you could have problems with that. Considering how flat your place looks there I would focus plantings on areas other than the low spots, any areas that have some slope to them or even on the high spots and avoid the lowest spots.
Do get a soil test and the main things you need to know are the PH (ginseng prefers low ph 5.5 or so would be ideal) and high calcium levels 2000+ pounds per acre, and decent levels on phosporous would be nice too.
Below are links to my youtube channel and to Billy's.
I have a couple vids on planting wild-simulated that you might want to check out and also several on ginseng hunting and Billy has some great vids as well. Check em out.
