I have been involved with two of these - out in the country, loooong driveways.
The advice given, two wire, direct burial or plastic conduit, is good.
Something you didn't ask - and perhaps already know the answer:
Light blinks:
How big of a transformer are you getting? 200A, 240V is 48KVA. Some recommend sizing the xfm down to the expected load.
One I helped with, was a 100A service, ~1000', customer bought 2 - 15KVA transformers. House had oil heat, propane cooking, no AC, and a 2hp well pump. Loading was well within 15KVA. And the lights would blink every time the well pump kicked on - and his wife complained.
With incandescents, a 5% dip causes an annoying blink.
Consider sizing the xfm and wire to 3% Vd or less. Yes, it is more money.
Consider 600V. The cost of the transformers should be about the same. For the same wire price, less Vd.
What I don't know:
Incandescants blink annoyingly with a 5% dip. I don't know if this applies to LEDs or curly-cue fluorescents.
