Can't help with a recommendation I'm afraid, but if you're open to a more DIY approach... Is there are any obvious damage? With the strong winds it may just be slightly misaligned, or a cable has come loose. The receiver should have a facility to show signal strength, perhaps someone with a ladder & head for heights (depending on dish location) could realign the dish while someone inside guides using the signal strength indicator?
Alternatively you can buy meters for ~€15-20 that will allow you read signal strength at the dish.
