How much does it usually cost to put in a NEMA 14-50 outlet?

Hey everyone, I got a quote for installing a special electrical socket called a NEMA 14-50. It runs on strong power, and they said it would cost $995. Is this a fair price, or should I ask someone else for a quote?

I invested $250 to have a 14-50 outlet installed directly beneath my garage panel. The cost can vary depending on the location you choose for installation; wiring for a 50 amp outlet tends to be pricey.
