I would contact Jews for Jesus...I'm like you; I'm not sure of any other available resources. What I do know is that Jews for Jesus have tons of resources available (i.e. books, tracts, etc.) When I was working in New York, everywhere I went I saw Jews for Jesus. I am also on their mailing list, and they are great about providing updates about their ministry regularly.
