I know this is an old post now, but if the OP never found something yet, or someone is looking for the same thing, I made this out of a replacement sprinkler stake, 1/2" male to 3/4" male copper coupling, and an Orbit sprinkler head. Total cost, $20. I put a low angle nozzle in (out of picture, I have a reg. Hunter nozzle in there) that came with the head in a nozzle rack. Works great, sprays only 2-3 ft. off the ground, and shoots out about 25-30 ft. depending on the pressure.
