Need Business Ideas (₹30L Budget) – Career Break Due to Special Needs Child

39F from Chennai. I'm a former Senior Product Manager and mom to a 9-year-old autistic child. I had to take multiple career breaks to care for my son. He's now in school but still needs my support, so returning to a full-time corporate job isn't easy.

I'm looking for business or franchise ideas with an investment of around ₹30 lakhs that can generate steady income. I'm currently considering an EV charging station but would love other suggestions.

Has anyone started a business in this budget? What would you recommend?
