Many country clubs and golf resorts provide caddies to work for members and/or guests.
If you’re looking to work as a caddie at a nearby country club or golf resort do a Google search for country club caddies or golf resort caddies and you’ll find many listings for clubs and resorts with a description of caddie services offered and how to apply to work as a caddie.
For example, here is where I got my start in caddieing –
Worcester Country Club in Worcester, MA
The Western Golf Association Evans Scholars Foundation web site has a Caddie Program Locator
It includes country clubs and also resorts in popular destinations like Pebble Beach, Bandon Dunes, Pinehurst, Streamsong, Kiawah Island, TPC Sawgrass, Whistling Straights and many more. (May be seasonal in some areas.)
Full time caddies can make $500 a week or more depending on the amount of time spent caddieing and where they caddie. Weekend availability is a plus.
