If you are not looking for unique characters, you might try to persuade thralls. They are most popular to maintain labour. You can find quite a few of them in Black Claw Trail and Brimstone Lodge (be careful of the second place - it has many other enemies).
If you need a unique, Bato is the most labour-oriented. But you can actually grow any of the characters in any way you want them. For example, I have leveled Kirilo (the "Chaotic-Alligned Orc in a silly cape", I assume), as a fighter to the point he became intimidating and making enemies around him lose initiative, which worked well with his Slippery trait.
If you tell me, who you have, as a saviour, I might point out some others with Lawful alignment.
