Rain gully problem to stop garage flooding in heavy rain.

Our garage floods a bit during heavy periods of rain as our driveway slopes downwards. The drain is not blocked. The rain gully at the front of the garage cannot cope during heavy rain. I am after a permanent fix to this problem. I am thinking that perhaps a second rain gully could be built into the driveway, leading to the current drain. This would then take the pressure off the current rain gully. Please see attached photos. Can someone suitably qualified/experienced please provide me with suggestions for a permanent fix and a free quotation for carrying out such work? Thanks.
