Source control, ventilation, and filtration are the keys to healthy indoor air quality. Dehumidification is important too.

Seriously, it is like asking "how much is a new car?"
A few questions come to mind: How big is the house, where is it located, how well is it constructed, how many people, is there a specific issue to be addressed or is this for overall geneal air quality improvement?
If someone were to offer an answe without asking at least all of the questions above, their gues is as good as yours or mine, probably worse.
The unit can cost the installer a few $100 or a few $1000. The installer can charge you a few $100 or a few $1000. There are a lot of variables. Rough guess, $1.5/sq.ft
sound like you are looking for a HRV been standard on new homes around here since late 80 ,s
do not know how you would retrofit one economically
Single story house?
Basement or crawl space?
Forced air heat?

Go to the American Lung society web page and look at the information they have on how to achieve clean air in your home. They have lots of information there. I wrestled with this question about a year ago and used their info to make my decision.
FWIW, We had a "super good cents" home in Washington state quite a few years ago, the builder put the bathroom exhaust fans on timers which ran for about 3 hours during the day while we were at work. I think it was a state requirement for air quality. It seemed to work quite well. That would be a quick and inexpensive method to move the air. You'd just need to know how many cf of air you'll have to move & set the timers accordingly.
If you have winters like us you would want to keep the HRV out of your cold attic. That is a problem waiting to explode.

Why's your house so humid? I'd look into the source of your moisture problem before looking for solutions.
They run $1,500 to $1,800 around here in NC
