school transfer to new buildings needs suppliers from China or Malaysia

Hi, we are going to transfer our school to new bigger and better buildings. Since we will have more room in the new place we want to expand our capacity and replace some old cabinets, desks, chairs, etc. … I was thinking maybe we can buy this stuff from China or Malaysia (price is a big concern here) the problem is that I have no clue on where to find those suppliers are and how to reach them I tried looking around hoping to find good manufacture or supplier in those countries but I can’t find a good trustworthy supplier yet and I was hoping maybe someone can help with direction or advice.

Btw, our school is in the Kingdom of Saudi Arabia.

Alibaba Manufacturer Directory - Suppliers, Manufacturers, Exporters & Importers is a useful place to start if you need to find suppliers in China.
Ths site itself is sound/legit/very widely used...but make your own commercial decisions on the suppliers you engage with.
