Would you take a pay cut just to make some extra money?

I have over 9 years of experience currently freelancing and a partime job that is paying 95k per month , the freelancing pays over 3 I am not happy with the full time 40hr work they want a whole product developed for 95k in a month should I quit I took it on to get some extra cash. But feels like it's just not worth the time and effort.
