How much will it cost me to get an electrician to install electricity into my shed. The shed is 50 feet from the house breaker panel. I would like it install under ground. I'll be running a light compressor battery charger and wood working tools.

We cannot help with pricing.

We do not know where your located, what the labor costs are in that area, what permits fees and insurances cost, and cost of materials.

Contact 2 or 3 contractors and ask for estimates for the same scope of work.

That and we don't know the draw for your equipment. Some tools pull 1 amp while my table saw pulls 10 amps all by itself. I'd suggest you get two prices from 3 local contractors. Ask them to price a properly gauged cable with 120 vac and then ask how much more for 240. Shops tend to grow.
