I am unable to get good proposal for my sister , please expedite the duas to bring a desire proposal for her

Walaikumussalam
For marriage proposal kindly recite sura Mumtahena after every prayer and recite following dua after the Surah
اَللّٰهُمَّ اِنِّيْ اُرِيْدُ اَنْ اَتَزَوَّجَ فَقَدِّرْ لِيْ مِنَ النِّسَآءِ اَعْفِهُنَّ فَرْجًا وَ احْفَظِهُنَّ لِيْ فِيْ نَفْسِهَا وَ اَوْسِعْهُنَّ لِيْ رِزْقًا وَاَعْظَمِهُنَّ لِيْ بَرَكَةً فِيْ نَفْسِهَا وَ مَا لِيْ فَقَدِّرْ لِيْ مِنْهَا وَلَدًا طَيِّبًا تَجْعَلُهٗ خَلَفًا صَالِحًا فِيْ حَيَاتِيْ وَ بَعْدَمَوْتِي
Ghusl is mustahab at all.if rest of the acts were correct inshallah Allah will accept.we are praying to Allah for the acceptance.
