Hi PC
1. As Nick states, use bog standard fenceposts with either caps or the tops cut at a slight angle (after melling them in) to keep the water from entering the posts and splitting the wood.

2. Put your posts three yards apart - this is the normal spacing. Place your two end posts first then string your bottom wire - this ensures you get a straight line for the rest of your posts. Depending on the length of the fence, and how taught you want the wires, you may want to brace the end posts with another post set into it at an angle. I would use three wires, top, middle and bottom to hold your net. You can attach it with strings, pull-ties, wire loops or you could hire a fencing stapler that they use to attch Rylock fencing to wires on stock fences.

Hope this helps
