I can’t tell anything about sources outside of SuttaCentral; I just don’t know, and maybe there are some.
On SuttaCentral, right now the Bhikkhu Pātimokkha is only available in Pali, but soon Ajahn Branhmali’s new English translations of the entire Vinaya will be added. So if you have a bit of patience you will be able to easily find the Pātimokkha assembled in one place.
If you don’t have the time, I am afraid, you will have to go through each individual rule in the Bhikkhu Vibhaṅga and extract the actual rule from all the surrounding text in both languages—which would probably keep you busy for longer than it takes for the new translations to be published… (hopefully)!
Once the new translations are on the site you will be able to view the English and Pali texts together side by side or line by line.
