How much would an electrician charge to hook electricity to my dishwasher?

And please don't answer with.. "Call them and price them" that is not what I'm asking. I'm looking for a general answer before I call them so I am prepared to get a reasonable price. My dishwasher, instead of having a plug in, it has 2 thin wires. My electric box is right underneath the floor where the dishwasher will go. It wouldn't take but maybe 25 minutes or so to do this, I just don't want to mess with electricity, I'm pregnant and it's not worth the risk. Thanks!
