There are two purportedly public domain Cebuano Bibles, the Cebuano ang Biblia, Bugna and Pinadayag Versions. They were published in 1917, so they are presumably public domain, however the Pinadayag Version has a wholly revised version of the New Testament from a date I can't find, and Philippine copyright law puts copyright as the author's life plus 50 years, but with these being whole Bibles, some different precedent probably applies. If you still need to contact the publisher nonetheless, unfortunately it is now being published by, still, the Philippine Bible Society. I've retrieved this information from "Christian Classics Ethereal Library (CCEL)" at https://ccel.org/ccel/bible/ceb_b.
