I tend to negotiate at ~$400.00, but that typically involves writing a custom child theme and plugins. Although i've done it for "whatever you can afford" for friends.
If I have a friend that can't pay what I find it worth, I usually just do it for free. As soon as someone pulls out their wallet, expectations go way up. Another good tactic I've heard is to put the value price (what you'd charge someone legit) and then discount it to their price, but show it all. Then they value it what it should be.
