eShakti (website where you can customize clothes by size and basic modifications) is making Jeans now.
I ordered a pair (first order with them you can get $30 off and free customization). I think my mom helped me take about 20 measurements. Then they shipped from India.
The jeans are a little more 'fashion' jeans than I usually wear (at least in part because store bought NOT to my measurements is always baggy and/or tight somewhere). But they fit me exactly. (No extra room, but not too tight either)
So long winded way to say, this might be something to check out if you can never find jeans that fit.
