Hi Arellia, instead of trying to find a tailor that could charge u a good sum for tailoring your jeans, hit a known fashion house, they normally have great people in charge of tailoring any kind of clothing, in my case, whatever the garment and the label, I always go to Hugo Boss, they have a great tailor, actually, the best I know to fix anything, from missing buttons to neck and sleeves arrangements. Call and find out if they can do watherever you neeed to do with your jeans.
all the best
