If it's your daughter that wants goats, will taking some to slaughter be a problem for her? They are cuter than cute, smart, have personality plus, but it can get out of control if you try to keep them all. It might be a good thing for her to know where meat comes from. You can't keep them all!
I suggested meat goats because the meat is good, you can sell the kids and they are not the commitment that dairy goats are. We don't have goats, we have hair sheep. I studied both and settled on hair sheep. We like lamb!
Our fence is 4' tall. I used 200' rolls of 2"x4" woven wire, 48" tall. We used 7' T-posts and have space to string 1 or 2 strands of barbed wire at the top. The horse pasture has barbed wire at the top, haven't got to the rest of it yet.
