Howdy, bajtarn. Welcome to the forums
Not much of a golf bettor myself, but you can occasionally find some props and futures at Bodog. Cris and 10Bet are also offering some action on Ryder Cup right now. Also see some action on upcoming European events at Bodog and Cris.
I'll do some more digging and see what I can come up with. In the meantime, feel free to venture around the best of the forum and happy posting.
