I would pay up to 75 on the big one and 50 on the small one and still make a proffit. The cell phones are a diffrant story, can't tell from pics. if any of them have batteries, some don't, do any power up? If they power up you can get more for them, if don't take the batteries out and sell the batteries seprate, scrap cell phone go for up to 6.50 per lbs. The fire extinquishers, some look like ss, don't know how many there are,I wouldn't pay more than 2 bucks ea. But then again I'm cheap.
