Yeah dead ones would be rewarded from Allah Swt by His will but as mentioned by others paying the reciters is not fine.Read these to clarify it more
قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " اقْرَءُوهَا عِنْدَ
مَوْتَاكُمْ " . يَعْنِي {يس}
It was narrated from Ma’qil bin Yasar that the Messenger of Allah (ﷺ)
said: “Recite Qur’an near your dying ones,” meaning Ya-Sin.(Ibn Majah)
Narrated Ma'qil ibn Yasar:
The Prophet (ﷺ) said: Recite Surah Ya-Sin over your dying men. This is the version of Ibn al-Ala'(Sunan Abi dawud)
Also see this which shows very clear evidence that dead ones could receive rewards,
'Aishah (May Allah be pleased with her) reported:
A man said to the Prophet (ﷺ): "My mother has died suddenly. I think that if she were able to talk (alive) she would have given in Sadaqah (charity). So, if I give Sadaqah now on her behalf, will she get the reward?" The Messenger of Allah (ﷺ) said, "Yes (she will be rewarded for that)."
[Al-Bukhari and Muslim].
The Prophet Muhammad (peace be upon him) used to go to the graves of the martyrs of Uhud once a year and also recite the verse of the Holy Quran. The Prophet Muhammad (peace be upon him) used to pray for them. When the Prophet Muhammad (peace be upon him) passed away, Abu-Bakr (Ra), Umar (Ra), Usman (Ra) and Ali (Ra) used to do the same thing.
(Tafsir Tabari, Tafsir Ibn-Kathir and Tafsir Qurtabi).
'Abdullah bin Abu Qatadah narrated that his father said: "The
Messenger of Allah said: 'The best things that a man can leave behind
are three: A righteous son who will pray for him, ongoing charity
whose reward will reach him, and knowledge which is acted upon after
his death.'" (Hasan) Another chain with similar wording.(Ibn
Majah)
Allah Swt and His Messenger knows best.
