Happy to be proven wrong, but USD 2500 seems unrealistic.

I would argue it's just one more convenient assumption that leads us away from a realistic estimation.
It seems to me USD 2500 is an idealistic best case scenario.
If I pay the remaining amount of $2166.42 to the delivery person over 10 years, that's about ₹1493 per month, which is over 6 times the cost of newspaper subscription. For that amount, yeah, they'll be happy to hang the paper on a wall.
With millions of people living in conditions where even safe drinkable water is not something you are guaranteed to get - 250$/year equivalent seems wild.
