how much to paid for a maid (Dakar)

Hello. I've just moved back to Dakar after five years away, and four days in I hear that my former maid already knows I am back in town, and she doesn't currently have work ... I'm feeling I may have little choice but to take her back, although hoping we can agree for just one day a week.
What is the currently acceptable fair price that Europeans pay their maids per day/week? If things haven't changed then it will be more than Africans pay but less than Americans pay.
