I'm buying quartz pillar blocks in bulk which I need for my mega-build.
I think 16 stacks will be enough, though I am not sure.
I am also willing to pay people (in negotiated goods or cr) to help me escavate the final room, which is 49x120x48. I was using a filler to escavate the rooms, but it doesn't get the ores...
I perfer to hire people with vajras or TC hammers to help dig, as help makes the task seem less daunting and does wonders for motivation.
Also, if someone with CC permissions is willing to program a turtle to escavate the area, that'd be awesome.
Payment for those who help mining: You keep what you mine, and cr or additional goods if additional payment is needed.
Payment for owner of Turtle: Half the ores mined by the Turtle and cr.
