To add to Skeezyks' post...

There are community mental health centers that can help your friend. There are also training clinics where therapists train themselves before entering practice. You can get low cost help from those clinics, which is a great option.

Also, you have the option to negotiate price for services. Not everyone will negotiate, but some places do have sliding scales. You'll just have to call a bunch of places and ask. However, the good thing is that community mental health centers can help you find that information if you want to go through them first.
