Mike, much depends on your business model. Since you state you are looking at a bread & butter operation, here's what I would contemplate. Assume F&B is break even, just a grill operation, not full kitchen. No wait staff, only counterman/grillman/bartender - all the same guy.
Pro shop - 1 general manager, preferably a women who can do the back office accounting, 2 shifts per day Dawn-2, 2-close. 1 helper. Inside 1 assit mngr, 1 helper, outside 1 starter and 1 ranger/range attend, if your place has a range. Gen. mngr works 8-5 to cover both shifts and the shift change.
Maint. - w/36, you can go a couple ways but I would figure 1 Super and 2 assit. Assit should be able to do Irrg and spray duties. 1 mechanic and 18-20 workers.
I would hire as many retired or part-timers as possible. Teachers, fireman and others who have days or summers off. Also empty-nest women. You'ld be surprised how many people want to work but only a couple days a week. This holds down # of full-time workers who need benefits. You might end up with as many as 30-40 workers but some may only work 1 or 2 shifts/week and it's easier to get someone to cover a shift if someone can't make it in. Also, it's easier to call-off workers when the weather is bad if they aren't counting on the paycheck to make rent.
Trade-off golf/range for lower base pay. Any employee who isn't friendly, is argumenative, or causes friction - FIRED. Once you put together the right atmosphere, and keep the course in decent condition, your rounds will take off - especially if priced right.
Also, make an effort to to do one or 2 small "projects" on the course each season. If the golfer see that money is being put back into the course, they tend not to bitch as much.
With a program like this, you should be able to staff the clubhouse for about $500,000 and the maint for about $650,000. So with materials and expenses, you can see how $1.5m is entirely in the ballpark but I'd be more comfortable closer to $2m until I knew what the taxes, insurance, utilities were. Also figuring that some capital re-investment is probably going to be needed.
If done right, you should be able to use a portion of the increased rnd rev. to offset the capital re-investment expenses. I would hope that you could get rnds up 60k for 36 but would never budget for more than 90-110% of the previous yr (high/low budget). Start building that rainy day/yr fund ASAP. If you can make it work on 40k rnds, and don't fall in love with one or 2 good yrs, you should be able to weather the cyclical nature of the business. That's $55/rnd to break-even. At 50 $44/rn BE, at 60k - $36.66. Conversly at 60k, you could be netting $1.1m for that fund (and winter in Fl).
I realize this is back-of-the napkin and there are lots of variables to consider, but it's a way to start to thinking about these things.
