Looking for a sperm donor -UK

Hi,

I am a 34, single woman, who is looking for a sperm donor in the UK. I have a daughter from a previous relationship, and don’t see myself in a relationship any time soon, or in the future. I would love to give my 3 yr old daughter a sibling, something which I never had.

I’m happy for any prospective donor to have minimal contact if they wish or none at all.

Can you please help?
