Recommendation for adoption agency/lawyer - I live in Northern CA

Hello - I'm new to this forum. Have been researching adopting for a few months. Would like domestic adoption of an infant. Would consider private adoption agencies/private lawyers. I live in Northern CA, north of Sacramento. I see a lot of advertisements on this forum - would love to hear other people's first hand experiences. Our goal would be to adopt within a year if possible. Would anyone be able to share your experiences with me, who you used, how long it took, and PM me? Thank you.
