Sources: all collections; answered in English in the Scholarly style.

Note: The retrieved sources are almost entirely from Rebbe Nachman / Breslov works (Likkutei Etzot, Sefer HaMiddot, Likkutei Moharan). Since you excluded Rebbe Nachman, only the non-Breslov material can be used — and the retrieved sources contain none that directly address segulot for marriage or parnassah outside that corpus. The Ta'amei HaMinhagim passages retrieved deal only with medical remedies (fever, worms, cold feet), not marriage or parnassah.

The sources provided do not cover this question outside the Breslov corpus. A proper answer would require sources such as Shulchan Aruch, Talmudic aggadah (e.g. Sotah 2a, Niddah 70b), Zohar, Shelah HaKadosh, or practical segulah literature (e.g. Refuah ve-Chayyim, Kav HaYashar) — none of which appear in the retrieved material.
