If your buddy is too late with a supplier try
www.yell.com and see if there's a shop near you?
As an aside before I install wheel bearings I always take the seal off (with a very small screwdriver)and pack with more grease as they don't come that well packed from the factory... I tend to use SKF,FAG or NTN marque.
If you're stuck for dust covers you can try to get a price from an agricultural supplies place also as another option.
