I know absolutely NOTHING about the process, but I think you're a great woman to even think about doing this for someone else! I've had three cervical cone biopsies, and have therefore been told my chances of carrying a pregnancy to term are slim to none.
To avoid the stress/pain/trauma of a miscarriage, I had the Essure contraceptive implants put in to block my fallopian tubes. Since it would take a miracle for me to afford surrogacy, I've had to accept that I'll never have biological children of my own.
Talk to a good counselor before you go through any arrangements, because even though a pregnancy wouldn't be your biological child, it may still be hard to give the baby up after nine months of constant attention to it's prenatal needs. I'm also glad you can discuss it with your daughter, because otherwise it could be confusing for her.
Good luck whatever you do, and know that one of the Mamasource women blesses you with her heart for even considering giving another woman this incredible gift. You, and your daughter for supporting you, are both very special women! With a Mom like you, she'll grow up to be a great person.
