This quest can be acquired from the Rattay Bailiff after asking the Innkeeper if anyone in the area needs any help. Once you have spoken to the Bailiff about the Skalitz refugees needing jobs, exhaust the dialogue options to learn where you can begin your search.
The bailiff will recommend that you speak with Alex, one of the Skalitz refugees who will be able to determine the best people for each job, and Konrad Hagen, a local wealthy merchant who is looking for a cook and housekeeper.
Ask Alex if he knows anyone who might be capable of water carrying and emptying latrines. He will talk to the refugees and ask them to assemble outside the Rathaus, but this will take some time. You can also ask him if he knows any good cooks. He will refer you to Agnes, a celebrated cook and housekeeper who can be found in the church.
Note: While Agnes is undoubtedly the best option as a good cook and housekeeper for Konrad Hagen, you can also wait until the refugees have gathered outside the Rathaus. There you will find a younger cook, with no experience in either cooking or housekeeping. She will be a terrible option for the merchant, but she will appreciate the job more and will therefore appeal to those who are role playing the good, honourable knight.
After asking Agnes if she wants to be employed by Konrad Hagen, she will insist that she is still employed by Father Francis. Choose the following dialogue options to ensure that she will agree to work for Konrad:
-- And why not? -- He doesn't need a housekeeper anymore. -- I shouldn't talk about it...
Note: You can choose to be honest with Agnes by asking what happened to Father Francis. This will require you to seek him out in Sasau and ask him why he is not coming back, leading him to confirm that Agnes is free to work for Konrad Hagen.
Once you have secured Agnes as the cook, wait until the morning when all of the refugees fit for work have assembled in the courtyard of the Rathaus. Speak with each of the refugees and exhaust all the dialogue options to determine what they might be good for. Note that Pickman, Rock and Tonda will offer something in return if you put in a good word for them. When speaking with Rock, you will have to provide him with a Marigold decoction to heal his arm, ensuring that he is fit for work.
Once you have spoken to all of the refugees and exhausted all dialogue options, you can go back to the Bailiff and tell him who you think is best for each job. You can choose anyone you like, but keep in mind that if you make poor decisions it will influence your reputation with the people of Rattay. For the best reputational outcome, choose the following for each job:
-- Pickman -- Vincent -- Tonda
-- Antonia -- Rock
Once you have assigned each person to a job, the quest will complete.
