Looking purchase Tile Set?

Is there anywhere I can purchase a Isometric tile set for building a strategy game. I want to build a fictional Alternate WWII Era strategy game. I’m looking to purchase art for it. Willing to work with a basic example as art isnt essentioal for now. Juts need stuff to code with


You might try on itch.io, but the variety is not great:

You can also search on http://opengameart.org/ and maybe try to contact an artist if you like his work, to see if he’d like to do work for your project.
