Yes you can get good success in these businesses. But kindly note that you are in the Rahu period which indicates hurdles and obstacles. Also in your birth chart 2nd house lord Jupiter is conjoined with Rahu in the 12th house forming the inauspicious Guru chandal dosha. Jupiter is debilitated in the Navamsha chart. Doing the below remedies is recommended for success.
1. Put Kesar tilak on your forehead or throat or Nabhi daily
2. Visit Shani temple every Saturdays
3. Read Hanuman Chalisa daily
