Your budget isn't really sufficient to buy much in the way of photographic lighting kit Barry, and I'm not sure that it's worth spending in any case for a task like this.

Given that you already know a bit about continuous lighting I would suggest that you use a few normal indoor lights placed appropriately so as to show off those aspects of the guitars you want to bring out. You could diffuse, bounce or flag the lights using sheets and similar to prevent excessive shine and blown highlights (and to keep the light off your background).

The main thing to watch for if you do this is to close the curtains so that you don't have daylight coming in as this will give a colour cast if you are not using daylight balanced bulbs. You should try to use all of the same type of bulbs in your lights so they are the same colour temperature and set the colour temperature in your camera to match. If you're not sure which is the right colour temperature, take a few test shots at different settings and go with the one that looks best on the playback screen.
