You can buy a board from us or make several of your own.
It is pretty cheap and easy to have boards made. Most places will accept online the gerber zip file included in the download package. Often you end up buying a multiple batch of some size but it is still inexpensive. The service we use sends 10 minimum. We buy the lead-free boards (often required in EU and other countries). Lead-free costs a bit more. You can order from any of the many board shops on the globe. You also can find many local board shops for less where you live.

We buy the black lead-free board using the default options for the rest.
So, make your own, or buy one from us. Your choice will depend on shipping costs and whether you want more than one board.
