Not to be rude to your friend, but $1800 for someone who just started it could be a lot. There are many vendors who charge similar rates after years of work. She has no experience. Paying $1800 to her just so she can practice on you is not ideal. Also, hiring a friend is one of the worst things you can do. If you aren't happy with the images, your friendship will be ruined forever. And since she has very limited experience, chances of that happening are very high.
