Cantilevered Garden Umbrella in working order (Saham Toney IP25)

This umbrella still works but the canopy has gone mouldy. We do not have the tools to take it off and put a new one on which is the obvious thing to do !!the cost of getting a new umbrella outweighs employing someone to do this for us so I am offering it to anyone who would like to take on the challenge!!
