As long as you have some binding posts, cheap speaker wire, a suitable feed line, and a convenient support structure (i.e. a mast), you can make a decent HF vertical in only a few hours.
In this video, Walt (K4OGO) assembles all of these pieces and makes vertical antennas for the Amateur Radio bands between 20 and 10 meters.

Here are some comments from Walt (K4OGO):
Build an effective and inexpensive vertical antenna for any HF band. In this video I show you how to make speaker wire verticals to cover 20 through 10 meters. #hamradioantenna #hamradio #amateurradio
