Here are some duas for sustenance, which i think this can fall into
Translit: Allaahumma inniy as-aluka ilman naafi'an, wa rizqan waasi-an, wa shifaa min kull daa-a
"O Allah, I beg of You useful knowledge, plentiful sustenance and thorough cure from all diseases (afflicting me)."
Translit: Allaahumma ighfirliy dhanbiy wa wassi'e liy fiy daariy, wa baarik liy fiy rizqiy
"O Allah, forgive my sins and give expansion in my home and grant me blessings in my sustenance."
Allaahumma ighfir liy warhamniy wahdiniy wa 'aafiniy warzuqniy
"O Allah forgive me, have mercy on me, guide me (to the right path), give me comfort and provide me with sustenance."
Hope it helps, Inshallah
