Pat Sisk's numbers seem like the most viable answer here, after updating 25% or so for inflation. I also think many will have higher than 11% payroll taxes.:
76 well-sized bunkers hand raked six days per week for approximately 28 weeks. Average $8.50 per man-hour + 11% payroll and associated taxes = $9.45 per man-hour.
Raking: $46,967 (4,970 man hours)
Weeding: 4,205 (445 man hours)
Trimming: 9,545 (1,010 man hours)
Ordinary Sand Addition: 3,000 (+/-)
Rake replacement/repair: 2,000 (+/-)
Total Cost: $65,717
Average per Bunker: $865
These numbers are for operating only. Capital projects such as renovation and drainage are a separate issue.

I ask similar questions. Once, about 2011 (the same time period) in the Midwest I asked a super at one of my high end public courses and private renovation clients the same question. For three day a week raking on the public course, the number was $50K, for the six day a week program at a nice private club, the answer was $250K. Can't be sure if either added sand replacement, etc.
Would be interesting to get some current responses, maybe from supers both with and without liners, machine vs. hand, private vs public, include the price of sand (which can vary from $35 to $145 per ton, etc. But, his basic format is a nice start to a formattable excel spread sheet.
Just a note, but 4,970 hours over 168 days (6 days/week over 28 weeks) equals a four man crew every day, each spending a full 8 hours (or 8 over the first half of the work day to get them done fast)Inquiring minds want to know!
