I have to agree with oomis. I also agree with frimet.
I don’t think a person can consider being a shadchan as being a job. We have an obligation as Jews to facilitate marriages and if you know of a good shidduch idea, I don’t think you are entitled to decide to withhold it pending a good price. It is NOT like a profession, where you would have the option to not take on the job.
As far as finding $1000 or not giving a candy dish or paying $1100 instead of $10000, I think some people may have a lot to learn about other people’s lives and struggles. If I can’t find $5 for my kids class gift to someone, how can you tell me I NEED to come up with that kind of money.
To me, $50 is a fortune, if I “found” you $100 you should know I missed out elsewhere. What a crazy concept that facilitating a marriage that was ordained by Hashem himself ENTITLES you to money I need to feed my kids.
