Sending My Friends Home

My name is Bill Smith and I am a chef in Chapel Hill, North Carolina. I have many friends who are immigrants. Some of theses people are employees, some are former employees. Almost all of the families have mixed documentation. They are worried that loved ones may be deported. I want to be able to put people on planes if they feel that they need to leave the United States. I'm not sure exactly how much we'll need and I'm not sure when I will need it. This is a contingency fund. There are eight families that I know that could be affected. Thirteen children under the age of 16. I have gotten everyone's travel documents in order. I'm afraid that there may not be much notice so I want to be ready to go at any time. I might also need to help with living expenses before people go if people are suddenly out of work. There may also be legal expenses. I thought if there was any extra cash, I would divide it up among these families if they in fact leave. Most of them have been here so long that they no longer have homes in the places where they came from. 
My plan for using the money is this: If I buy plane tickets, I will do so on line using my own accounts. If bills need to be paid , I will write checks, again from my own account. I will keep careful record of all the expenditures, that all donor will be welcome to examine. If everyone leaves and there is any nmoney left, I will just give it to the families, probably by sending them money orders since they will by then be back home.
