Feeling Lost in Reviving My Career as a Soft Skills Trainer – Any Advice on TTT Certifications?

Hi! I want to revive my career as a Soft Skills/Corporate Trainer. I have previously worked as a Supervisor/Process Trainer at Infosys BPO Ltd for 3 years. I have an M.Com degree and am currently pursuing a Diploma Programme from ISTD. I'm also preparing for the BEC (British Council of India). I am clueless about how to get a job and what TTT Certification to pursue. Please help me.

Regards,
Surbhi

Could someone please suggest a reliable organization that conducts the Train the Trainer (TTT) program that I could participate in?
