A dealer will likely charge a minimum of $1500 (probably more) and will more than likely not have the expertise or include all of the parts that
should be changed while doing a T-belt job.
I went with Geordi here on the forum and I think someone provided a link to his services above. Cheaper than any shop and definitely more experienced. He is quick, precise, and comes straight to your house. My guess is a dealer will likely have your CRD for at least a day (likely more).
I'd suggest getting the IDparts.com kit, or at least replacing the same items the kit includes:
