One of my best friends is a foster mom to six (she is unable to have children of her own). She definately does not do it for the money, and she loves the kids like they were born to her. It takes all her money to take care of the kids.
My first thought is if your hubby is not on board, then you should wait on it. It can put a major strain on the marriage. I have seen this in my friends situation, just something to keep in mind.
Also, the situations the kids come from are heart wrenching, (as I am sure you know) so it will take a lot of emotional energy as well. We have cried together many many times for her kids.
I think it is a great opportunity, I have thought of doing it myself but my husband does not feel called to do it.
I admire your heart for children. My advice is meant to be gentle and sincere. I hope it helps.
