Ask HN: Can someone refer me to a designer that doesn't suck? 17 years ago
She is a member of our tribe and used to working with 2 uber open source computer scientist geeks that we are at (rmdstudio.com). She is actually dating a young oxford post doctorate mathematician.
But she doesn't work for people, she only works with them. So instead of asking her to send in a portfolio, perhaps you could contact her and let her know that you need some design help.
