I’m LF a BS to make Enchanted Thorium Breastplate. I have all the mats & will pay. 
Still looking? I can do it, but your mats will be of no use as you’ll need to make a plate wearing class trial or death knight or something on my server to get it.
Thank you for the offer but I spent a lot of time farming the mats & I can’t send mail to the toon I made on your server so I wouldn’t even be able to pay you. 
If you can’t do cross server, you might consider posting requests on your realm server forum instead. This forum isn’t generally used for trades/adverts unless it is for any server, and even then very rarely. You might have better luck finding someone on your server that way.
You don’t need the mats, get a pet on your server (worth roughly what the mats go for), cage it on your alt on mine, pay me with that.
Can use dataforazeroth.com and chuck in my server and character in the search boxes and click pets then untick collected to see which ones I’m missing.
And if ya want, can use that site and browse the other no-longer-obtainables I have. While you’re on my page, click recipes, untick collected, tick collected on alt, untick not collected - then expand the advanced tab, tick unobtainable (collected). Can mess with the professions tab and only look at blacksmithing if you want to reduce the number for easier browsing.
This player from your server cluster has it on at least one of their characters according to dataforazeroth
caveat: they may have the pattern on alts that aren’t on your server - no way of telling. but it’s a start!
other caveat: data-mining hints that all the OG ZG patterns may make a come back in patch 1.07 or after. so if you can’t get hold of those players you may be able to learn the pattern yourself on an alt in a few months!
