Unity HDRP shader expert needed to create realistic vegetation

I am looking for a Unity HDRP shader expert to help me create realistic vegetation that's very efficient, dense and good looking in all lighting states. The shader should have all the basic stuff for vegetation: wind, translucency, etc. + should have (along the static branches and truck), some camera facing billboard branches (placed in the middle of the static branches), to be easier to achieve lower poly count and density.

I do have examples/reference clips. Also I own multiple vegetation libraries from Unity asset store (from Nature Manufacture and ALP), that can be used as texture source.

I want to work with experienced people. I need someone that can provide photorealistic results in Unity, not "blockchain game experts", NFT, etc.
