Happily, I've found a landscaper who took the task off my hands. The rock is in, and I'll plant a lilac and add mulch to the dirt area that remains.
I confess, I headhunted this guy from the modern bungalow. I saw his crew working there and got his number, and later confirmed that he comes well-recommended.
What's great about him is that he has fixed a bunch of little things (for free) that I had not asked him to. Tightened a sagging gate, pounded in loose fence nails, pulled out some old juniper stumps. He fixed the broken conduit. He looked at my sprinkler system and had a forecast of doom, but then came back and said, "It's not as bad as I thought."
He's a keeper!
