Are you sure that you want to come back? There are other places to live besides the West Bank.
I just feel sad because there are so many people who would love to make Aliyah but cannot for one reason or the other.
I think that with your career, you should have trouble finding work. Try LinkedIn and Monster and similar sites. Use your contacts. Don't be embarrassed to call or email people who you worked or studied with before you moved.
To make extra money, consider using your skills that you gained in Israel to help you. Don't underestimate how much you can earn teaching Hebrew or even making video blogs (with advertisements) about your life and experiences. I can't imagine that there are any organizations that will pay for you to come to the US since there are so many trying to get people to make Aliyah but you can ask for donations using a crowdfunding website. I have no comprehension of how much money you need but perhaps you can raise a portion of it.
I see that this is an oldish thread but keep us updated so that we know how you make out.
