Is there a speed train from Guangzhou to Yiwu or Guangzhou to Shanghai?

I am looking for the fastest and cheapest mode of transport to Yiwu Zhejiang province in China. Flying is quite expensive and i cant afford it. The other alternative is for me to get a speed train to Shanghai then speed train to Yiwu. Please help. How long do the two distances take and how much do i pay in usd value? How much is flying from Guangzhou to Yiwu in usd value?
