بسم الله الرحمن الرحيم
Recite Ya Mughni (يا مغني) 1111 times after Isha with durood 11-11 times before and after for prosperity and blessing in rizq (livelihood). And after Maghrib salah recite surah Waqiya and ask your family members as well to recite the same. In-shaAllah, it shall bring prosperity and blessings in rizq.
Allah knows Best!
