It seem to me like you are trying to jam a square peg into a round hole. Trash collection, at least in major cities in the US, is done either by some branch of civic government (for example New York's Department of Sanitation), or by a private contractor, usually on a long term contract (Greenwaste Recovery in San Jose).
It's pretty far removed from what could be considered a free market. Yet it's not expensive (at least compared to things like phone service, water, or cable), its employees tend to be reasonably fairly compensated, and as you mentioned, it works. ...even if that reality might not be popular in libertarian circles.
If anything trash collection in Cairo sounds more like something approaching a free market than what large cities do in the states.
