Nothing wrong with a properly sized 220v extension cord
I did theatrical electric for many many years and we often would have 50-100 foot runs of 220v extension cords.

for 30 amps, you need at least 10 gauge wire

If you are DIY a new 220v outlet from your breaker panel, you can also use plastic conduit. Its a whole lot easier to use than metal rigid conduit or even flex

for 220V , 3 wire is fine
