You unlock assasination missions by doing those silly little side game missions like mowing a lawn , picking up litter, etc.

And you unlock those side game missions by progressing in the story.... I don't believe you can do the picking up litter until you've gotten to a certain rank. Do you actually know this for certain? If so I don't mean to be arguing against you.

In my experience, this is in fact how it works.
