Successful single woman in Sydney looking for a sperm donor

Successful single woman in Sydney looking for a sperm donor. I am a single, educated successful woman hoping to start a family. I work with children on a full time basis and would desperately love to care for my own. I am looking for a sperm donor, who is fit and healthy and willing to undertake STD tests and be available for assisted conception. I would prefer to have limited contact with the donor after conception but I am happy to negotiate this. If you would genuinely like to assist, please contact me. Thanks.
