Some great thoughts so far, many thanks.
Some things to mention. In all likelihood, I can't envision the course coming back to the clubhouse at the turn, with certain areas of the property off limit to our course designer, so very likely there will be a halfway house/hut somewhere out on the layout, whether it is after 8, 9, 10, 11, whatever.
In keeping things simple, a minimum number of staff will be working, thus no valet parking nor any bag drop area serviced by staff. Oh, there could very well be a driveway up to the front entrance and the ability to drop your buddy/clubs off at the door, but you'd be on your own, no staff.
Out-of-the-box thinking includes going with a "manager" or "director of golf" but no CPGA pro. Teaching lessons isn't what this course will be about. A nice practice area will be built for warming up and/or dropping by in the evening to work on your game (albeit being located several miles from town, doubt that many would do the latter). A small area inside the front entrance should meet the needs of everyone with a small selection of shirts & jackets available for purchase, with sleeves of balls, and bags of tees, perhaps a few gloves, at the front desk. Just the necessities.
The underlying theme here is to keep things practical. Small nice touches, though, could go a long way, and may not require extravagant spending.
I'll add a bit more later but I hope to read a few more comments in the meantime. Thanks so far.
