Sounds awefully high to me. My electrician bill was around $750 and that included the subpanel, installing 4x4's for subpanel mounting, wiring up the subpanel, two intermatic timers, wiring the timers to the polaris and main pumps, wiring the light, the light switch, an outlet, and all required circuit breakers. They dug all trenches, installed conduit, and back-filled (can't believe your electrician says back-filled by someone else).
