You can self publish through DriveThruRPG and Amazon, they take care of printing and shipping for a piece of the action.
Cheers! I haven’t yet had the opportunity to explore Amazon’s POD quality, but am hoping for something a little fancier than DTRPG.
You can consider Lulu, but DriveThru has a large user base, multiple print options and can do cardstock components (which Amazon cant do).
No reason why you can't release on multiple platforms and see which one does best for you.
