If I were you I would call every Ford Dealer in a 2 hour radius to see if they will do the work. It is an expensive repair and like said above, your car will not pass inspection with the codes.
If you have a good job like you say you do, I am sure they will let you have a day off to get your car taken care of; otherwise you won't have a car to drive to work.
Just IMHO - But this is what I would do with my car. I always call around to see where I can get the best service, especially with Ford Dealers.
Oh, and letting cars idle for long periods of time is bad for the Catalysts. It is actually the worst things for them.
