You have a B Tech civil and a passion for cooking and have not done well in IES.
You have a big list of wants money, luxury, name and success, it is not impossible but needs hard work, few are lucky to get lucky breaks. Even if you are lucky, you have to be prepared when it comes to you.
Passion for cooking is good as part of spending time, to convert it into a high paying career needs a lot of work. You need to have a basic understanding of the different cuisines, the ingredients, have a website, make videos of yourself, participate in shows and contests, if you are good you can make it.
A more practical approach would be to focus on the skills that you have in hand. IES is a competitive exam that would need skills of how to tackle the exams and subject knowledge. If you see any MBBS doctor doing their MD/MS/Mch, some of them take the PG competitive entrance exams 2-3 times because of the small number of seats and the huge number of candidates. Most of them do a part-time job and then prepare for the exams.
So, my suggestion would be to take the IES exams once more. There are good study materials, practice papers available online, choose a good coaching center close to your home and prepare with a single determination that you have to succeed. Once you get a good result, that would be your stepping stone to a good career. You can also plan for GATE/UPSC/SCRA exams.
