I didnt have time to read through all the posts, but i wanted to point out that when my son had his bris, my husband was told that the going rate to pay a mohel was around $450-$500. A few months later, i was talking to a neighbor and she said that some mohelim get up to $1000 or more!
My point is that everyones ‘going rate’ is different. Shadchanim who are more well known usually get more, but when i enter teh shidduch scene for my children, how am i supposed to know who is more well know or more chashuv?! tell them straight out what you charge. if you’re vague, you cant be upset about not getting paid.
