请问下面这句话有语法的错误吗？还有木有更好的表达方式呢？

Question

An old acquaintance called him, saying that there was a recruitment of an assistant，and the wages of which were high.
大概意思就是，一位熟人告诉他，他那里要招聘一个助理，工资很高。

Answer 1

有错误，用of which中间不能用and,
可以改成：An old acquaintance called him, saying that there was a recruitment of an assistant， of which the wage was high.

Answer 2

你的意思是要表达 一位熟人告诉他，说新来的助理工资很高是不是？是的话那语病有误了，可以这样表达，An acquaintance told him that a recruitment of an assistant who had a high wages.追问

嗯嗯，我的意思是一位熟人告诉他，他那里要招聘一个助理，工资很高
