Repairing stuff has been out of style for a couple decades but it may be coming back in style again. Good for you finding a niche like that. Right now its dryers, maybe next month its TV's. I have heard that there are lots of tv's thrown out that could be fixed for $20. There are also people that just do "e-waste" recycling. They get broken tv's, monitors, pc's, and so on and either fix or scrap. They often get the stuff totally for free or even charge just to haul it away. I'll give you an example , my company just moved and was paying an e-waste company to haul away pc's and monitors, I got a laptop and a desktop for free out of the recycle pile before they hauled it away. The PC was completely working , it was just old. The laptop had no power cable or battery so I am gambling and buying an $8 power adapter from ebay and see if it boots up. I would imagine you could get scores like that on a weekly basis but you would not get that from craigslist, you have to go straight to businesses.
