my aunt is going to buy something from chinese suppliers that's almost £10k inc massive shipping bills (something like £2k. considering it's shipping what's basically a house from china to africa it's a good price and worth it, but again these suppliers can just take the money and ship over something rubbish, and it;d be difficult to chase up. so what'd be the best way to find some sort of reliable 3rd party who'd make sure the chinese people got their money alright and my aunt gets her things bought and shipped in good condition?

THANKS
p.s happy new year
