There are a lot of people who prefer to make their outfits when they hold high standards for the quality of the cosplay. However it's understandable that people don't have the time to learn how to sew. This kind of sounds like the situation your in.
So what you want to do is search for a commissioner, somebody who you want to pay to make the costume for you using your measurements. You can try looking through this thread here:
Commissioners on cosplay.com list what they can do there, you can read through and possibly find somebody that has the skill-set for all of Stein's pieces...or possibly commission different pieces from different people. You can look through their galleries to see what kind of work they do for themselves and see if it's the quality you're looking for. You can also check out the commissioner review threads for extra input.
I sew my own costumes, but don't take commissions so I can't help you out...but hopefully you'll be able to find somebody who can with that information. Good luck!
