$85/hr seems a decent contract rate, even affordable by many standards. Keep in mind that as a contractor your taxes are greater and there are no benefits. $25/hr is very, very low for a skilled developer (that's almost junior-year intern level).
You can also look at median salary data for a region at http://stats.bls.gov/bls/blswage.htm
Edit: after looking at stats for the NY metro area, it looks like you should expect 90-110k/year on average. Make sure you're clear on your units ($/hr or k$/yr) when you negotiate.
