Lawn sprinkler maintenance cost estimate?

I have a 2000 sqft lawn with an in-ground sprinkler system split into 4 zones. Lately, I’ve noticed the sprinklers aren’t watering evenly, and at least a couple of sprinkler heads are broken.

I’m looking to get the system tuned up — specifically: • Replacing the broken heads • Adjusting spray patterns for even coverage • General inspection and maintenance

Has anyone in the area had similar work done recently? What did it cost you for parts and labor? Any local companies you’d recommend (or avoid)?

Thanks in advance!
