Extend Timber Decking

Hello, looking for someone to extend my existing timber decking by around 4m x 3.5m (approx. 14m²). Needs to be properly tied into the current decking and extend out into the garden. Access is easy via the driveway. Budget is around £1,200 but open to quotes depending on materials/work involved. Happy to provide photos – please get in touch with availability and a rough price.
