Gnoahh,
Keeney windflags will work dependent on how much you want to spend there are graham flags. You may puruse them here.

Remove the bottom grip and put an appropriate size pipe cap drilled for a spike to go into the ground. Cost was about 15 bucks average compared to about 50 bucks per for the fancy ones which I thought too flexible when extended causing the flag poles to move in the wind.
