The meeqaat is the meeqaat of the one who is delegated to do Hajj

A man died two years ago and he was not able to go for Hajj. Now his family and children want to do Hajj on his behalf, but they do not have enough money to enable them to send one of them from Pakistan to do Hajj on his behalf. Hence they want to delegate one of the Muslims who live in Makkah and pay him the expenses of Hajj and the hadiy (sacrificial animal). Can Hajj be done on his behalf in this manner, and will he get the reward?.
