Sub-Meter GPS advice

Need some advice.

We have an opportunity to do some location work (test holes, etc) over several thousand acres. The area is somewhat remote, has sparse control points and a lot of vegetation (planted trees, forest, canopy).

I think using static to create more control for RTK will be too costly over the large area...also the conditions would likely cause communication problems rover-to-base.

I believe that the accuracy needs might lend itself to backpack sub-meter GPS. The crew would need to move quickly and stake locations within 30 feet of given coords.

We know nothing about sub-meter equipment, having never used it. What pitfalls and/or advantages might we have with it in this situation?

Thanks for the input.
