How to end homelessness in America?

I realize that this is probably a very complex question and that many people and organizations have spent years on trying to come up with solutions for this problem. I don't know exact statistics of the number of homeless people in the United States but judging from the visits that I have made to large cities and smaller cities, the homelessness level in large cities is a lot higher and they seem to have many homeless people. If it was up to me to come up with a plan to get people off the streets and back on their feet and I had unlimited funds,  I would first start out by getting statistics on the number of people living on the street. Then I would build shelters, and build enough so that everyone could be taken in. People would receive all services for free at the shelter, such as food, showers and sleeping arrangements. They would also get free employment agency services so that they could eventually save up enough to move out of the shelter and stand on their own two feet. And in an attempt to prevent homelessness, I would set up a program to which a person could go to for help if they felt like they were on the verge of becoming homeless. The program would provide some financial help as well as a plan to get out of the hole. That way the cycle of homelessness doesn't just keep going and I wouldn't have to keep building more and more shelters.
