Start off with 200$ per hours
Then go to like 3k per days
Up to 15k per weeks
50k for a month (you did say on the unofficial forums you were gonna do a month max?)

Then people in each sect of era society can get it what they desire. And buying in bulk time saves you money.
Something along these lines.

Could always add cheaper or free stands section/room that people can rent for like 15 minutes at a time that instead charge a tax percentage on sales.
