The criss cross would work if the pond level didn't fluctuate. Go to
dockbuilders and do a bunch of looking around.
I'm a do-it-yourself type of guy, and I bought their hardware for my pier. I priced their stuff, and the pieces/parts to build it myself. Their parts were pretty close to my cost in pieces parts in Stainless, not including my labor to fabricate the pieces. If I knew of a hot dip galvanized place close by, I could have done better on the pricing. As it was, I bought their hardware. The pier will be built and installed this winter. I'll be putting posts into the pond bottom.
