Morro Bay spearfishing guide?

Looking for a guide to take my boss and his son spearfishing. Both are experienced and will only be in the area for one day, August 18. I've called and emailed all the dive shops in the area and found one guy but he's booked. Anyone want to spend time (paid) with two great guys spearfishing? I've worked for this family for 10 years -- good people. They will need to rent gear as well...
