A liner over the dirt floor costs less than full encapsulation. HomeAdvisor reports $2 to $4 per square foot for basic encapsulation and $3 to $10 for more extensive work.
Full encapsulation runs the liner up the walls, seals the seams, closes vents, and adds moisture control. See the difference in crawl space encapsulation and vapor barriers in Columbia, SC.

Every estimate follows the same five steps. The details change with your crawl space.
