Trade Anyone?

I have a softball-sized rock with 50-75+ golden yellow zoos w/ yellow mouth and very long skirts and a sprinkling of GSP that I'd like to trade for a rock of the same size with something different on it.  Can be some other variety of zoo, maybe a leather or possibly a mushroom if it's unusual etc.  I just have way too many of these darned yellow zoos (they were given to me by a neighbor who moved).  I really only wanted a few, but he gave me 3 rocks with them, and I'd rather have some of this space freed up for something else.  Pm if you have something like I described, thanks!
