Hello Omkar,
Its a very nice thing that you want to become a professional footballer. You can move to cities where football is popular like Bengal,Goa. Nowadays even Bengaluru is contributing to Indian football.
I would recommend you to join a club which plays in competitive lower level divisional league so that you will get some idea of what it takes to be a footballer.
Keep an eye on popular clubs conducting trials for U-18 or U-20 and practice basic skills and work on the skills most required for the position you play.You have to work hard all year or years together.Opportunities are very less, so you got to be ready when it comes. Most of the I-League teams have youth teams so you do have to appear in the trials conducted by them.

Join a local club. I can only tell you about Delhi as many clubs conduct open trials every year for their division. They always look out for fresh talent as they want to get the promotion to a higher league so look out for open trials. There are several facebook pages that inform you about the trials so check them out + there are even open trials for Santosh trophy which is a state tournament, a lot once you play in that tournament it'll lot easier for you to get clubs. Practice and always look out for trials! Best of luck!
5080 LPA is an average salary if represent the first team of an AIFF registered football club. It's a huge amount for an average middle-class family but less if you compare with IPL or other international leagues. It's not a scheduled salary but I took an approx estimation to understand. It depends upon your signing contract with the club including match fees and bonus. After ISL the standards are higher in crores.
