For wheel spacers you shouldn't need to take it to a bike shop, just have a machine shop make the spacers. Do you have a set of dial calipers? Measure your stock spacers, stock wheel width at the machined face of the hub, and new wheel, and distance between the axle adjusters. Do a little math to keep the wheel centered, Make sure the pulley and brake rotor are the same distance from the centerline of the new wheel as the old wheel, have some spacers turned up and you're done. Shouldn't cost much at all if you can figure out what sizes you need. If the wider wheel still allows you to use factory brake hardware, and doesn't require an offset pulley, it shouldn't cause too much trouble. Got any pictures of the parts? As long as this new wheel has the same bearings as the old wheel and fits on the axle, calculating spacer widths shouldn't be a big deal.
