really agree with what @loepuenkyou suggested if you want to buy mining equipment then buy it locally because I'm sure now computer equipment has been spread evenly in all cities in the world
I was facing the same issue recently and want to buy mining stuff to mine Ethereum. The first result i got is that i shouldn't deny the black market opportunities because there are almost no offers available for the majority of those who are need of this stuff.
In the countries where it's not that easy to find a local provider, no ways but to check for them in the black market (unregulated market). It's a little bit risky but maybe efficient more than contacting factories for it.
