Does anyone out there have any advice regarding outdoor fences
(backyard type)

I can think of several score different kinds of fences that will vary
100x or more in price.

and what they might cost?

A big factor is where you live. Figure out what kind of fence you want,
measure how long it needs to be, and call someone in the local phone
book as ask "About how much would it cost to put in X feet of Y fencing?"
