There are custom modders who are trustyworthy but arent necessarily on the trusted list around here that offer this type of thing.
@AMF may offer this type of build and they are trusted here.
Not sure the price you were quoted but based on the current price of gold I would expect the case and bracelet alone to be nearing the $14k USD mark or above, easy.
Not trying to steer you away from your current modder and I know that I didnt really answer your original question, but I just want to make sure you arent getting scammed.
