Really? It depends if the family is in one of two mindsets
A) This shadchan and only this shadchan will bring their shidduch (aka Avodah Zara)
B) This is part of their hishtadlus to show Hashem they are trying their best. (Pretty extravagant but understandable, shidduchim is a hard parsha)
Also, what does 10,000 dollars get you? A meeting? A promise to “keep you in mind”? A guaranteed marriage? At least 10 yes’s from guys? A date that will at least get to 5 dates?
What are you paying for?
