I live in Israel and I know of many causes that seem to be up your alleys — all of you — in which I am personally involved in.
1) kollel in which a group of learning avreichim learn with working men.
2) tomchei shabbos in which the organization gives chickens to the families for shabbos and yom tov
3) kuppa shel tzeddakah in which poor families – including single parent homes – receive money for food and basic living expenses
If you are interested in donating to any of these causes – I can help you make a donation, or send you more information about the organizations mentioned above. All donations are tex deductible in the US
