Uber Lab Farming does not give enough gold

With the introduction of the new instant buyout trade I'm finding that as a lab runner I cannot sustain enough gold to purchase the gems I need for the font. Players no longer reliably respond to in-person trade

Suggestions:
1. Make izaro drop more gold
2. Offer a font crafting option to sacrifice a gem for gold
3. Make the chests at the end reward more gold, or have a random chest spit out a moderate amount of gold.
4. Have argus drop gold based on how far into the labyrinth he is. This could incentives runners to make a pit stop to kill argus, without making it an imbalanced gold farm when he is in room 1.
