Welcome Bhavay!
Yes, getting those oblique holders in India is hard. But I was the recipient of Prasad's generosity! Also, if your budget allows, there are reasonably priced ones from Philippines that you can get shipped at much more reasonable rates than US (in terms of shipping atleast).
Once in a while, you can spot a Speedball Oblique popping up on Amazon or Ebay.
Nibs,
1) Hard! But there are a couple of costly sources though!
Inks,
1) Once again hard! But keep an eye out on Amazon, you will get some once every couple of months.
2) Alternative: I use regular fountain pen ink and add a bit of Gum Arabic.
Paper,
1) Probably the easiest, I've found some really cheap and lovely paper for practice that behaves very well.
2) BILT has been my favorite so far, the other options have been the paper used in the regular 100/200 page ruled/plain notebooks which are hard bound (the paper on this is thin but there is no bleeding and it holds well).
3) Tracing sheets as we call them are a lovely way to practice and figure out where you have gone wrong.
Here is a trick I have used,
- Use water soluble ink
- Use the thick tracing sheets (not the thin white ones but the thicker cream paper)
- Practice with a guide-sheet below it
- Use a cloth to wipe it off!
This works well, but it some nibs and water soluble ink don't function very well because of the viscosity and the inability of the ink to stick to the nib.
