burger, the standard econo fence around here for that purpose (and partially to keep critters out) is a t-post, field fence, barbwire combo.

typical construction is t-post every so many feet (i think about 8') then after every 4 or 5 t-posts and at corners or gates, put in concreted chainlink posts for strength. stretch on a 4 or 6 foot field fence, and complete with 2 or 3 strands of barbwire on top. i'm sure costs vary around country....call a few fence companies and bid it out. you can hang signs all over them, they last for years, if you need privacy on some sections you can insert slats vertically through the field fence. if you get a true field fence, the openings are small at the bottom (to keep out rabbits etc..) and they get bigger at the top.
