Repairs - Otherwise Known as Aaaaargh!!!!!!!

We had some serious water damage in our garage during a recent storm and, when we contacted our insurer, they agreed to do the repairs but - and there's always a but, isn't there - they want us to install an additional down pipe before they'll tackle the repairs.

While I agree an additional down pipe is probably highly desirable exactly how we're to get this done I'm not sure. Pisces, while a wonderful man in many ways, is not a handyman by any standard you might like to apply and I'm disabled so that means we're unable to do it ourselves. If our recent experience in trying get quotes for another much bigger job (costing around $1500-2000, we think) have been unsuccessful - we have so far approached seven tradespeople for quotes and of those only one has turned up and then he only gave us a guesstimate on the back of a card - what chance do we have of getting someone to come and install one down pipe?

Doesn't look hopeful, does it.
