This is an easy rewiring job, you won't need a specialist at all. But if you can get into the motor go ahead and check the contacts. If the wiring is bad everywhere it's most likely bad inside the motor as well. Somewhere in the recesses of my mind there is a blow-up diagram and if I can find the url I'll pm to help take the motor apart.
Inside the motor, there may be brass/copper contacts that need soldering to the new wiring (some have this, some have pigtails) but you can do the soldering yourself no problem. Look up tutorials on youtube to learn how to solder and you'll be fine. I can tell you're mechanically inclined, you'll have no problem whatsoever.
And while you're in there, check the grease and replace if necessary, if it's a motor that uses grease I should add.
