Have you tried contacting Tent Valeting Services at Bolton? They may have some spares. Alternatively try a caravan accessory shop as very often they have a number of varying size awning poles that may be compatible.
If you can find a broom handle the same diameter as the inside of the pole,banging it in will support the straightened bit. Failing that,conduit perhaps.
