India is already one of the cheapest service providers for such launches - ISRO puts 36 OneWeb satellites in orbit - https://www.thehindu.com/sci-tech/science/isro-successfully-... (They are ofcourse working to create a reusable launch vehicle too).

They can build it in a few years though. It takes money and can be done overnight but there is nothing about that that costs 10 years. 10 years got to the moon - from a much lower base. 10 years means you are starting with college graduates and building it from no previous experience - or you already have a lot but only are putting minimal budget into improving.
