Generate Normal Map from Diffuse

The diffuse map image is image 1; the final rendered result should be as in image 2. I will provide a diffuse texture and need a clean, ready-to-use normal map for the game to be created from. The final normal map should subtly highlight surface imperfections while maintaining edges, contours, and overall lighting faithful to the source. Delivery items: • 1 ambient map in PNG or TGA format with the same resolution as the original diffuse texture • 1 normal map in PNG or TGA format with the same resolution as the original diffuse texture • 1 displacement map in PNG or TGA format with the same resolution as the original diffuse texture • A source with layers or editable (Substance, Photoshop, or equivalent) so I can fine-tune settings later Please note that the shading must be clearly visible and closely match the original image. I have used materialize, but the results were not satisfactory. I appreciate proven experience, so please link to previous texture or material projects that demonstrate your normal mapping skills. A few brief notes about your workflow or preferred tools (e.g., Substance Designer, CrazyBump, Knald) would be helpful, but specific examples of completed projects would carry more weight. I appreciate prompt feedback and clear communication; I'm ready to start as soon as I find the right person.
