Material development needed - USA

[Streetwise]

I'm in need of a material to be created. I have the source high res scans, plus a physical sample to send. PM me if interested, plus costs. This is for the creation of a wood material shader that has properties to the attached file. As you can see, the source file shows dark wide bands and light grain, but when the sample is reflected, the opposite happens and the wide bands become lighter and the grain becomes darker. The physical sample is essentially very smooth. The narrow threads of grain are very slightly indented (bump map) but very slight. The attached file shows a render that I created with a material that I made, but it needs to be much closer to the physical material.
