if its a one shot deal, the best bet is a generator.

if its a long term use location direct burial cable, or even get a

That's the best idea for a long-term venue. Runing cables without a
transformer would require very heavy cables and the cost would be
quite high. By the time you bought and buried the cables for a 110 or
220 volt solution, you could have paid for the generators and you
wouldn't have a trench to fill in.
