Copy a USB hub PCB

I have a pcb from a usb hub, which I can send you a photo of. I need to have a gerber file of this board and probably a few modifications done to it. This pcb the will then need to be produced, so the gerber file needs to be made with production in consideration.
If you need any details, I will of course try to provide as much as I can, but I only have a real board and the specifications for the ports.
