Fireplace surround (Bradway, Sheffield. S17)

We are in need of a fireplace surround maximum 4ft/120cm wide. It is to be used in a play we are staging in November. Ideally wooden and fairly plain but other designs and materials might work for us. If anyone has anything they think might work for us to repurpose we would love to see photos. We can do a certain amount of repair and it will most likely be repainted so it doesn't have to be perfect. Thank you!
