“以公司最小的成本换来最大的利润”用英语该如何说？

Our company will get the most gain with the least cost.

gain highest profits with lowest cost

Trades the biggest profit by the company smallest cost

上面的都还可以，不过正规的是gain the maximum profits at lowest cost,最重要的就是那个at

trade the minimal cost of company for the maximal profit.
