listen to my bro...I want to add something though...
The plastic fence is really fast, faster then the turf.The turf is slower but you have way more control on it.I recommend that you use the fencing on the inrun, and the turf on the kicker and landing.
prices (home depot): turf, about $20 for a 10X10 piece : plastic fencing, sorry I can't remember the price...
build a jib 101, is another possibility for sufficient amount of information on materials and prices.
