Shop making help

So I wanted to make a shop since i've amassed quite some items now. I tried googliong shop generators, found two, one is asking for money and the other one procurement, it seems only generates shops from your stash.

Problem is, I have only 4 stash tabs and I won't be able to buy more until may atleast, so I have all my items on different characters' inventories. Unfortunately, procurement only does stash tabs.

Does this mean that I have to individually link all my items and make spoilers and all that shit myself?

If it is not the 1week domination, its doesn't matter to put your stuff in spoilers, because poe.xyz will index your shit and IF someone will need something that you have, he will find it through this site. And forum trading is useless piece of shit. So, put all your stuff in one big spoiler and just wait. Of course you need to check if your items is findable on xyz, maybe you did something wrong.
