I'm sorry to read some of the off putting comments. Coming here is a PERFECT way to enhance your efforts to seek information and support. You might get the specifics you seek at GS but we are a family of loving, caring people who WELCOME you and look forward to being a digital part of your quest! Good, bad, right, wrong...WELCOME!!! I LOVE you and yours checking into the process of promoting family and inclusion.
Now personally, I'd like to encourage adoption over surrogacy, but my very best friend in the world has a wonderful seven year old daughter now through a selected and paid donor. Her daughter is AMAZING and their life has been amazing. You do not have to be married. You MUST be stable. Stable usually means gainfully employed (not wealthy), healthy both physically and mentally, and able to provide a nurturing environment for the healthy rearing of children. That's it!!!
You can SO make this happen. I encourage you to heed the feedback about prep work. Do your homework and DOCUMENT DOCUMENT DOCUMENT. Keep a running date log of events, efforts, findings, milestones and a calendar for planning and structuring the process.
Lastly, COME TO GS!! You will always find someone willing to give you a hug and welcome your greetings and concerns! Life's too short to speculate over something requiring action. Set your course and make it happen!
