How can I say this, nowadays this society, I think your son who went to college to make money, is much easier than you two. There's very little in the way of sure-fire jobs anymore, and, in your family's condition, it's just a matter of renting a booth, selling stuff, and finding a slightly less skilled business. Now there are a lot of low-cost entrepreneurship, there are also part-time opportunities, will not affect your son's studies, some online franchise, or do agent opportunities, are also low-cost, I do not know where you are, if you need to give me a message to see if I can give you help:)
