Ruling on taking money in exchange for searching for a suitable wife

Question:
Who says: "I will not search for a wife for you except for a sum of money!" What is your opinion?

Answer:
I am not aware of any harm in it, provided it is not merely intercession for a fee. Rather, he searches and investigates and informs him about her: so-and-so is suitable, or: she is not suitable, so he exerts effort.
As for intercession: one does not intercede for a fee, such as interceding so that they marry him. However, there is no harm in searching for a suitable woman for a fee.
Q: He knows many families and fathers due to his old relationships and acquaintance, so he searches for me, for example?
A: If you appoint him as your agent to search and pay him a wage, I am not aware of anything wrong with it, but it is not permissible in intercession.
Q: What is the difference between it and intercession?
A: Searching and investigating is like a broker, while intercession is saying: "Marry so-and-so, for he is a suitable match."
Q: No, it is exactly like intercession, for he has known them for a long time and has prestige with them?
A: He does not take a wage for intercession, but as for searching until he tells him: "You see, these are suitable, and these are not suitable."
