Cheapest online MPH program?

I am CIC certified and have been doing IP work for a few years. I’m looking to relocate. The area I’m considering relocating to seems to be competitive. The IP jobs I’ve seen want either acute experience or a masters as a substitute.

I can’t get past the screening for these positions since I only have a bachelors and don’t have acute care experience.

What’s the cheapest online masters program anyone has found?
