Please suggest me-govt. job ? business ? ca ?

After getting b.com degree, i tried for a job with handsome salary, but in vain. Then i joined cpt at age of 22 years. Now i am 25 years and 4 months, still doing ca course. My ca final attempt is 18 months away. I am feeling pressure from parents and relatives about getting merried and job. I am feeling helpless. I don't know what to do? There is less time for me to set career in any field due to age factor. If i choose to go for Govt. job, there is less chances because i am not prepared for them. ( maths, G.k., reasoning is not good). My choice is to set my own business but i lack enough money for that because sources is limited. I can't do a small business or general shop etc because i am ambitious or it is tough time to manage financial needs with less earnings. I am confused. I need practical advise.
