Detailed Log Section STL Design

I'm seeking a skilled graphic designer to create a detailed 3D model of a log section and convert it into an STL file for 3D printing.

Requirements:
- 3D model of a log section, size 16"x3"
- Moderate detail with texture and knots
- Convert model to STL format for 3D printing

Ideal Skills and Experience:
- Proficiency in 3D modeling software (e.g., Blender, Tinkercad, etc.)
- Experience with STL file creation
- Attention to detail, especially in texture and natural forms
- 3D printing knowledge is a plus



Summary

***View attached photos for reference***

A vertical tree branch that is straight, highly detailed in the bark, 16" high by 3" in diameter, with two stub cuts at the top, one facing off center towards the left and the other stub cut facing off center, toward the right. one stub cut at the bottom and one stub cut about two-thirds the way up the branch.
This is explained in a attached drawing, with measurements.  The branch is flat on the back side (so it will lay flat on a wall). The finished drawing needs to be converted to a STL file for 3 dimensional printing.  
The bark on this branch should be very detailed and match what is shown in the photo attached, but better quality.
This is what I need right now. I have other designs that will go with this drawing but at a future date.
Please contact me with any questions or clarification needed.
