Cost of a new horsebox floor

[SouthWestWhippet]

My current floor is wood, pretty sure it is on the way out - looking a bit ropy by the jockey door. Would like to replace with galvanised steel but would settle for marine ply.
Its a Bahill double pony box so jpretty small, rear unload only.

Don't suppose anyone has had this done and know what sort of money I'll be looking at paying? Obviously I know it depends on exact size of box and where you get it done but a couple of ball park figures would be great.

thanks

Mine was around £1600 for a big 3 horse truck. That was for new metal, wood, buffallo board and having to have my partitions altered because they were too big for my new floor
