I want a baby

I want a baby. Adoption isn't something I'm interested in. I know it's a bit unconventional but I know it's been done plenty of times before where an arrangement is made. My BF doesn't seem interested in having children with me but I want kids. NOW. My decision is my own. I'm fine with that. Any suggestions for finding a donor ?                         
Everybody is asking my age. I'm 36. Planning life isn't what I need to wait for. I personally don't have time or patience to waste on a man that doesn't know by now if he wants a future with me. Nor am I in the mood to wait on the right guy. I want a child and yes I would like to be married and settled but it hasn't happened and I fear that it won't. Some women aren't meant to be wives I guess, but I'd like a child at least. I know the responsibilities of being a mother. Which is why I was wondering how people make these arrangements when they want children. Or if someone maybe has gone through the same thing.
