To get a one off board made, £400+ is the cheaper option. It probably has custom software/firmware on that board. Is it a double layer or 4 layer board?
A board like this would be a ball ache to remake just one off, and would take so many man hours. The labour alone for a technician to remake this board would be the big cost. Without a schematic I doubt any PCB tech guy I know would take it on.
If the board they copy is not even working - it could take a few attempts to get a worker.
Sorry - I think you have buckleys chance on this.
I agree that chip in the middle (some sort of micro controller) is doing everything on this board, the rest is just support components which don't usually fail, if this board is completely dead it will be that big chip and it will have custom firmware so if its dead there aint much you can do

at least without a replacement chip or firmware.
But be nice to know the exact fault as if its still being detected by your
pc that would be a good sign. Or maybe just the regulator has died? Could try powering it up and checking your getting 3.3v or what ever the main reg kicks out.
Looks like the board is powered via the usb 5v, see if any thing it coming out of this chip. Pretty sure its the regulator.
