my iswara front converted to LMST.

if you want to do a proper conversion, will cost over between 1-2k, as you need to change most of the front chassis/bumper mounting points, fenders/bonnet

headlamps brand new original (recommended) is around 330 per piece/660 per pair.

the rest using 3rd party/taiwan materials. still needed over 1k.
if you cheapskate and do hackjob/knocking/drilling, used or non ori headlamps, then perhaps can do under 1k. however upon collision, your chassis is going to take a huge beating. not to mention night driving could be bad depending on the conditions of the headlamps you gotten.
