Budget Projector for my setup. Any help would be great.

I have a 9 by 9 impact screen with a 6 foot overhang (Not sure of terminology) with sides. I am going to ceiling mount the camera, but after reading here, I am even more confused about projectors. I have maybe $300 to spend on the projector and will gladly buy a refurbished or used projector. I am looking for suggestions. Thanks so much ahead of time.

I've been using an Epson Home Cinema 1060. Full HD, 3000 lumens. Mounted to ceiling behind mat. I'm upgrading to a 4k shortly. I'd be willing to sell with mount for $300.
