Just run some TEK cable (at least what its called in Canada). Its used for Hot Tubs, I ran mine for 90 Feet from my house panel to a sub panel with a 60amp GFCI. Cable is good for under ground no conduit needed as it has a metal sheath under the weatherproof outer layer. Shouldn't cost you more than $150 US for the cable., wire it with 240v and 40amp breakers and 240v ballast so you use half the amps. You can also take put in a 15amp 120v at the sub panel for other equipment.
Dont get the power at the pole, the meter is at the house and you would be bypassing that and stealing. pay your bills and be safe.
