First thing go buy you a good roping horse, 10k oughta get a pretty fair one. You'll need a good stout saddle and a 35' rope unless your a Buckaroo then you'll want atleast 60' or maybe a 100' they sure carry lots of rope.
Then your gunna need some dogs probably a couple curs or a catahoula's and 3 or 4 hanging tree cowdogs
If you don't have a half top trailer to drag them in when you get'em roped you'll need to get one of them too.
Fence materials, lots of wire and t-post cause you'll need to mend yours and your neighbors fence after you and them dogs run them calves through all them fences, but don't worry about that cause aint going nowhere their surrounded by ocean all away around.
Or you can skip all that and just do like Dun said
