Hopefully that labor cost includes them removing and replacing the FD from your bike, should be much less if you carry just the FD in to them.
Sorry I can't be of any help as I've never had to replace that input seal, but unless lots of special tools are required I'd think it should be a fairly easy do-it-yourself job. Good luck.
