Yeah, you're right there are too many variables. I wish there were a simpler way of calculating how the store could impact the ones around it.
Thanks NathanMuir, i'll definitely consult them first, it makes sense to just analyze statistical data. I guess i'm just concerned if it's right calculation, and I really don't want to pay someone to do it for me either. But i know a few people who provide these services.
I was hoping for a program which gives close estimates to how much I would affect the competition, consumer-wise. It would be nice if Google came up with something like that for small businesses. Anyway guess I gotta do this old fashion way, because if it were that easy then there wouldn't be any risk involved.
Thanks guys!
If this was an essay, i would get a D so far.
