Small Wood Koi Pond with Accessories

I'm in need of a compelling design for an above-ground, small-sized koi pond (up to 500 gallons). The intended material for the construction is wood. Additionally, the design should incorporate a waterfall feature, underwater lighting and plant zones. Ideal freelancers for this project would have a solid background in landscape and structural design, specifically with experience in crafting unique koi pond experiences. Knowledge in suitable plant choices for pond zones is also preferred. Your creativity will be relied upon to create a harmonious blend of these features in the finalized design.
