Adjunct pay small private college southern CA

*Correction on pay: My pay is abysmally low (with a masters)is 1600 in small private college. Phd's get 1800. 10 week semester, 40 hrs (and you all know the many hours out of class.. I added up 70 total!) Can I get anyone out here to give me a similar scenario (small private college).. and your compensation.. so I can try and negotiate (don't laugh, I know they will prob say .. buh bye)..
