I got my entire front bumper and lip painted for $100, granted it's the same Mom & Pop shop that re-sprayed the entire car just 6 months before. It depends on who you know, the kind of paint you're using, and what sort of prep work is needed. I got my parts in that weird flat black / primer that most come in. So I just roughed it up a little bit and dropped it off. My front lip is permanently attached, so it was all sprayed as one.
