My cousin just signed up for 40 days of prayer at the Kotel and wound
up getting married after, so I thought I'd pass this gem along ...
There is an organization, that will allow you to send a ben-Torah to
pray at the Kotel for you for 40 days. In Jerusalem, these '40-days'
are considered a famous segula to get your prayers answered.
I've seen also people who recovered from illness, got jobs, found lost
objects, and did teshuva through this site. The website url is:

I also know a few of the people who daven, and they are incredible
human beings. The money goes to a very worthy cause!
