Thank you David, Paul, and Ron! Some good suggestions in your replies!
Where I go in the Leeward Islands the maximum tidal range is one foot, so a lot of the time there is almost no intertidal zone... crazy huh?
Anyone have experience in requesting/paying folks who work in a scuba business to grab you a good sample of sediment from the sea bottom off the edge of a coral reef underwater?

I have found that, although the tops and sides of the rocks are good, the bottoms of the rocks may hold the most micros. One person can brush fairly well, but a two-person operation, one to hold the rock and the other to brush and hold the bag, is much more productive. I have obtained many micros, live and dead, using this method.

Whenever possible, take a small backpack to hold your sample and sieves, small kitchen sieves with at least two different-sized meshes, Sift only small samples, dividing them into separate bags, so that when you sort out the micros later there will be a greater percentage of them.
