Honestly, “chaimberliner,” has got a real good idea going. I too have a small questionnaire that I give friends of mine who are looking to get married. Also, handing a questionnaire to your shadchuns can help them match you and another accordingly, knowing at least a little info about each party, so the date will not be completely mishmash. I will gladly help anyone who is single. It does not matter how old a person is. There is a mate for everyone on this earth. For the record, I do not consider women or men over the age of 30 to be old, that is nonsense. (& thinking you are old and undesirable at that age will only make your self esteem, & the chances of finding anyone suffer). Furthermore, If I set a couple up, and they end up getting married, I would not want to be paid for the service. Knowing that I helped someone find their besherit is enough payment for me. Rather have that money given to the couple to help for wedding expenses.
In conclusion, the questionnaire is the way to go, if it isn’t being utilized already. Good Luck on those looking for their besherit! Just don’t lose hope, whether you are 18 or 80, there IS someone out there waiting for you.
