lemony: If you are single and flexible, you have a leg up, in that you can take one of many jobs anywhere. If you have some skills, or can pick them up fast, there are many odd non proffesional jobs that are listed on various employment sites. (israemploy for one). About cleaning houses, the stigma attached to many jobs in the US is absent here, and in reality, many jobs are a very real contribution to the mitzva of yishuv ha’aretz. As a entry level highly skilled worker here, I made just 15 shekel more hourly that a cleaning lady, and while you might think it strange, Jewish women do clean homes, and a common avreich job is sweeping/ washing building stairwells and walkways. The guy I sat next to in shul ( for a while, I move around alot) is a tow truck driver. In the US, this conjures up the lowest of lowlifes, here, the guy is a ben olam haba. Come with the attitude that you will succeed with help from above, that you are mkabel the yissurim, and will be willing to adjust, and you will iy’h thrive.
Note one: This all applies in the religious side of society. In the other, snobiness abounds, and you are judged by how many degrees you have.
Note two: The snobbiness on our side revolves, unfortunately, around labels and name brands. You will need to fit into some “box”. There is also the box of ‘crazy American’, but its not recommended for most.
