I have a brother who is working for his 3rd company in probably 5 months. If your husband finds a good company, then that's a decision for you to make together. I have done many things to try to make ends meet, but it's a joint decision--recognize (by what it sounds) that your husband it trying to be responsible for his family finances, and in many places the economy is not the best; but I guess you have to weigh the cost vs. benefits.
Good Luck
