My idea will not seem new to you, but perhaps this is the best solution for such a difficult move. Why don't you hire specialists for this move? I know that you can get a quote for the Singapore movers service if you visit the dedicated online marketplaces for moving companies. For example, I can recommend this site
https://www.wisemove.sg/ to you. Here you will definitely find all the advertisements from local companies that can help you with moving to a new home.
