How to do big trades? (when trade window is not big enough)

I want to buy a Mirror but obviously 900 ex don't fit in a window and you can't split the Mirror.

How do people go through with these kind of trades? Is there a protocol for this?

Thanks in advance <3

can buy intermediaries like doctors or just trade for mirror shards
wouldn't go forwards with any sort of "just trust me bro" scheme

Collateral. Hand them 600 ex, they hand you a 600 ex item. Next trade is remaining ex + item for mirror.

I thought about this, buying 7 House of Mirrors (I already have 2) but the only people selling them is literally me and another guy from Korea and at the price he's asking buying 7 from him would be as expensive as buying the Mirror, but thanks.
