No, that's $20k per certain number of man-days a month, with those man-day/months ending after a year. If I agree to 8hr/month of support for a year, that doesn't mean if you don't contact me for a year I will give you 96 hr at the end of the year. This is incidental, anyway. There are many ways to structure a job to end after a time frame. 20k/year is just referring to a job that brings in 20k, that you know will be over in one year.
