I did mine myself for about $200 including the Timer. I had to put a GFI outlet on the house and then run my twist lock recepticle off of it. I dug the trench by hand (I would never do that again. Rent the machine) which had to be 18" deep. Then I ran my plastic conduit. The city required me to use individual wire rather than romex. They required the gound wire to be insulated not bare.

I have my pool pump running off of its own breaker on my panel which luckily i had an extra one of.
