Maternity Pictures / How Much Should I Pay?

Kailyn • Navy wife + mom of 2
With my first I had a friend do them for free but she doesn't live near me anymore. I found this other military wife who makes a living on her photography business and she is willing to travel 30 minutes to my location (I'm on bedrest but planning on going into my backyard). 
She is charging $300 for a family session which includes an outfit change, at least 2 hours of shooting, 75+ images and full access to the online gallery. 
Is this a good deal or should I look for someone else in the area? I like to support small business people starting out but we don't have too much extra money.
