LS Men's clothing will do MTO trousers for somewhat less than $300. You should be able to get MTM for about $300. I don't know if they can copy your existing pair, but it wouldn't hurt to go there and bring them with you.
I sent them in initially due to a sole that was breaking apart. They did the recraft for free since the bottoms showed know wear.I took them into the store, and they are stretching them out. I'll give it a few days and try them again. I only paid like $150 for these on closeout, so I don't feel like I can push this too hard.
