with john and me ___(help)him,Me Fisher built a stone wall around the garden

With John and me helping him, Mr. Fisher built a stone wall around the garden。应该是Mr.Fisher吧，打错了。
这里是with的复合结构，with sb doing,动词help 与其逻辑主语John and me的关系是主动的，所以用-ing形式,doing也可以表示动作正在进行。
例如：With the government providing fund, many companies survived the ecnomic crisis. 有政府提供资金，许多公司渡过了经济危机。
当动词与逻辑主语是被动关系或动作已经完成时，则用with sth done 的结构。
例如：With my homework finished，I turned on the TV.
作业做完了，我打开了电视机。

helping
必须用动名词
