You other option would be to seal the whole thing once you have finished with some clear acrylic varnish but you said your doing it on the cheap

Reasoning wall paint is water based and will wipe off ,gloss and satin wood is oil based and will not just wipe off the walls

There is no substitute for preperation, cutting corners will only cost more in the long run. IMO
