It's the ultimate employers market currently. I ran an ad a couple months ago. I had well over 200 responses. I specifically stated in my ad "only those with a minimum of 5 years of verifiable flatwork experience need apply". That being said, at least 50% of the applicants had zero pressure washing experience at all (even had a software engineer with 20 years experience apply).
After weeding through the 10 or so that fit my qualifications, only 6 passed the drug test. Tried all 4 remaining men, picked the 2 best workers.
Run an ad on Craigslist (I believe its only $25.00) or in your local classified ads.
