Urgent Structural Wooden Lintel Installation

I'm urgently seeking an experienced carpenter to construct and install a structural wooden lintel over a doorway. This needs to be done as soon as possible.

Details:
- The lintel isn't merely decorative but is intended to provide structural support, so experience in building structural supports is required.
- The timber of choice for this project is pressure treated wood, known for its durability and resistance to decay.

Ideal Skills:
- Extensive experience in carpentry
- Expertise in structural supports
- Familiarity with pressure treated wood
- Capability to deliver within a tight timeline.
