Timber Staircase & Railing Repair

Looking for someone experienced in timber repairs to fix damage to our wooden staircase and handrail. There are several areas where the timber has been scratched, chipped and gouged, with some deeper damage along the edges. Ideally, I’m looking for someone who can: * Repair and fill the damaged timber. * Sand and smooth the affected areas. * Colour-match the existing dark timber stain. * Refinish the repaired areas so they blend seamlessly with the rest of the staircase. I’m hoping to have the staircase looking as close to its original condition as possible without needing to replace any timber. Photos attached for reference.
