Sorry, but you are not doing it correctly. Unfortunately the weight of a shidduch lies upon the parent.
You must call a shadchan and tell them you are sending in your childs’ resume.
A few days after it was mailed, you MUST call the Shadchan and ask to go over the resume over the phone to answer any questions.
The Shadchan is inundated by resumes, and if you want yours to stand out, you need to follow up.
The suggestion (made by you) that the Shadchan meet your child personally, at their convenience is also a plus.
Putting a face to the resume, in person, will always put your child on the top of the list of appropriate shidduchim.
Been there, done that. (twice)
