@waqasch1 bro To be honest i didnt really faced any particular bottleneck (as such) in this project since i dod all the working on parts and availability before choosing this very rig.
A heads up can be, stick to toyota for your project vehicle; due to vast availability of used and new parts. Secondly; lets be honest, due to the level of craftsmanship available here, small to big failures are common for these old boys — you can find most repair available up north in case of failure (and they do happen).
I have shared all facilities, google map pins and contact persona above; still if you have any specific question; please feel free to ask!
Cost i am not sure To be honest, since a bunch load of things had been procured, again, i remain open to questions.
Thanks a lot for your kind interest and patronage
