A strong paper shredder to use for 2 days (Loftus Road W12)

Obviously not the actual one in the picture but something robust enough to shred paper continuously for 20: minutes at a time. Our community centre has a backlog of paperwork occupying crates and boxes we need to use for other items. We’re in White City. We want to clear the decks before we close for Xmas so we can start the New Year as paper free as we can be …It’s literally all l want for Xmas other than to escape cooking any dinners.
