LF Chinese/Half-Chinese Sperm Donor near OR

I am seeking out a sperm donor of Chinese decent, in honor of my late husband as we never got a chance to have any children ourselves.

The main genetics I’d be seeking would be hair and color along with similar facial structure, but other traits like tall height and slim build, interest in mechanical things would be wanted, they just aren’t necessary.

AI is preferred, but NI is doable should a couple of attempts fail. I am looking for a donor, not necessary a coparent, but involvement with the child or financial support is appreciated, though not necessary.

Thank you
