baseupgradecost How much gold does it take to reach level 15 factory and HQ? (level 7 factory and level 8 HQ right now.)

~1.45m - 2.75m for HQ (this is an estimated guess)
~1m - 1.5m for factory (potentially)

Millions of coins. I'm not sure exactly how much because I don't know the cost for each level up, but it's probably over a million. Maybe even 10 million.
