Professional piano movers don’t cost that much (I’ve had my grand moved twice). I’d never attempt it myself, even for a moderately sized upright! On free pianos - usually there’s a reason they’re free… They’re often inherited, old, under-maintained and need a several thousand dollars of work to bring up to a decently usable standard (the felt degrades, so all the damper and hammer felts often need replacing, possibly even strings). But spending that much on a new Yamaha would probably get you something better sounding…
