If this issue is only that the width of the fork's dropouts isnt wide enough, as mentioned, a local shop cant widen the dropouts and ensure that they are evenly spaced between the center of the fork. It isnt a tough job and wont cost much.
If the issue is not only that the spacing isnt wide enough, but also that the dropouts arent square with one another, then its a bigger issue. It can still be adjusted, it just isnt as quick of a fix.
Rear dropouts on older bikes(70s and 80s steel) are coldset(permanant adjustment) most any time new wheelsets are used. Its a relatively common and easy process.
I would hope REI would have the tools to properly widen your fork, as they have certified mechanics.
