I don't know anything about this stuff, but if I were the pegulas, this is what I'd do -
Build a stadium with a retractable roof and pay for the entire thing. Bring in multiple concerts throughout the year to help generate income, but also host a wide variety of other events like auto shows, home and garden shows etc. Make it a year round buisness. Again I know nothing about anything, that's just my thoughts if I had unlimited money
