Is this a reasonable/common request from them?
If you have Quark Express and know how to use it, then their request is not unreasonable.
If you have experience in page layout, it is not unreasonable for you to do the work. (If you don't have layout experience, don't take the job!)
Do not assume the originals will be Quark documents, check with the potential customer before giving your price.
Usually layout would be charged by the hour, I think, and you really need to look at the documents before you can see how much work is involved.
Either charge by the word for the translation and by the hour for the layout, or charge by the hour for everything, or give them a single inclusive price for the project.
