Looking at your horoscope you have Retrograde Mercury in your birth chart and therefore not a very strong horoscope to indulge in business. Also you are in the main period of Sun and the sub period of Rahu till December 2015. Jupiter the 10th lord is in the inimical distance despite being exalted in transit. Some improvement can be there after July 2015.
You should do the following remedies:
1. Put Haldi / Kesar Tilak on your forehead daily.
2. Recite Rahu mantra “Om Brim Rahave Namaha” 108 times daily
3. Keep water to the Sun in the morning after bath.
