There are a lot of costs and red tape involved in adoptions. For the couples willing to go through it there is a great reward. One area that may help with some of the costs is your local church. This is a strong pro-life community and there are churches that may be willing to help with the expenses. Catholic Family Services may be able to help or at least give you a reference to check somewhere else. There are many organizations that help mothers and one could easily imagine that there would also be assistance for couples who want to adopt children.
I hope things go well for you. Keep up posted as to how things are progressing.
