1000 warheads?? please refer any international journal, you will know that india has 80-100 warheads and pakistan has slightly more at around 90-110 although that figure would increase in the future with new military reactors under construction.
Do you even understand what making 500 warheads...
this is the reason for the increased cost. if the IA orders arjun mk-2 in bulk, CVRDE can negotiate for ToT of imported parts which lowers the cost by almost 30% and taking it down to almost $5.5 million which is what the price should be
