Info on agencies in Ohio?

Hi! I'm just starting to research agencies and was wondering if anyone had information to share about Adoption Circle, Gentle Care, or Adoption Link in Ohio (or any other Ohio agencies that might be good) or about American Adoptions. I'd love any personal experiences or recommendations about these or other Ohio agencies. I'll be adopting as a single mom, age 45, so any agencies that are particularly good for older/single parents would be especially appreciated!
