I know of several people that do this.
In fact, one of my clients does this as goodwill to divorced/battered women in partnership with a shelter, as she was once a divorced woman and is empathetic to people in hardships.
I'm not suggesting that you're like this, of course...but sometimes, the glass is half full too as compared to a number of answers I've read.
While the majority of people are in it for profit - sure, but not everyone is.
There are some people that are in it to make a scam, but there are some people that are willing to make a modest profit as well.
Make sure the deal is reasonable and worth your time and money.
Check their sources, past clients, etc.
If you have any questions, continue asking.
