Installing a 220v outlet

Anyone here an electrician or know one?

We recently rented a washer/dryer for our new house...but the plug is thick, for a 220V outlet, and we just have a standard outlet...

Looking online, it seems too complicated and dangerous for someone to...

attempt it at home. Anyone know how much it would run to have a 220V outlet installed?

Well, I asked my Dad and he said it runs about $300...in case everyone is faced with a similar situation.
