We are building as we speak. Labor is running about $3800 (this is probably on the cheap side, but there is a bunch of competition in the S Tex area), Wire, t-posts(10ft), one strand of predator wire for top, runs about $10500 (from D&D in Seguin). Figure about $800 for concrete, and then there is your pipe for corners/braces. I am using all 2-7/8. You can shop pipe, but figure about 1200 ft per mile. This depends on how you want braces,, etc built, how many gates, etc. Current market on 2-7/8 is about $ 1.70/ft You might want larger pipe for the braces, gate posts etc. Larger=more $. Probably could get by with 2" line pipe. Another expense to factor would be fenceline preparation. Dozers and maintainers also command a nice sum these days.
Let me know if you need any additional info. ANY fence is an investment these days, but aint much cheap now.
Another issue is the type of wire. A lot of people are going to this solid 8 ft tightlock type wire. Using my low bidder price, the 8 ft solid runs about $1500/mile higher than the 2-47 in pieces run. Couldnt justify the additional expense when my builder charges the same using either type.
