Gina79,
Have you tried attending adoption info. seminars (either live or tele seminars) in your area? That would be a good start to get all the information that you need.
You don't necessarily have to choose local agency to pursue international adoption. If you'd like I can PM you couple of agencies that I have chosen should our last IVF attempt fail. They conduct tele seminars all the time. Let me know. Hope this helps.
I am so so sorry about your loss.
Good luck,
Vinita
