Yes yes yes. For years I've been hoping for someone to launch a business to solve this. It exists for dress clothes but I'm not sure if anyone is doing for jeans. I want to be able to just send in a pair of my favorite jeans and have someone churn out any number of new pairs of the exact same dimensions in any fabric/color I want. No more wasting time in miserable shopping malls trying on tons of pairs while being subjected to terrible background music.

Just did some quick googling for "custom tailored jeans" and there seems to be a few things out there, but not sure how good the service is. Might be worth a try
