Hi Guys,
Thanks for trying to help! Appreciate it! I hired a freelancer to convert it for me. It was quick as I needed it so urgently!!
Actually, I know Acrobat Reader can read .ai file as well, but I think my .ai file wasn't pdf readable as it must be vector form. So guess, a vector program should do the trick, but I did not have the time to do it!
Thanks gentlemen!
