We are looking for a plastic stake (recycle okay) to replace wood stakes for the land survey industry - need to be 48' long in a 1/2' x 1-1/2' dimension. These must be rigid enough to take impact of hammer driving into the ground. Any extras like inch graduations, a flat head, slot near top to hold flagging or any benefit to user would be a good upsell. We currently go through truckloads of these items each month. Need prices with delivery to Florida USA.
