I have seem some information go through Google in this service:

Executive Jewish Dating  22647 Ventura Blvd. #230

customerservice@executivejewishdating.com
Telephone: 1-800-655-0361

I was a member of theirs and had a great experience. I was able to
meet people that I otherwise would have never come across. Although it
is not their process, I was even able to meet my counsellor during my
membership, as we lived in the same city! My question is if there any
organizations  or individuals in the West Hollywood area that are
interested in organizing a singles event?

Sounds like more of a question for a west hollywood forum.

Not everyone has had a good experience with this service:
