I need a 3D model of rusted sword with PBR textures

Hi Guys, i need to make a 3D model of ancient sword.
I have the photos of that sword and 3D model must look EXACTLY the same.
Model will be putted into Unity 3D, so i need PBR textures of that sword too.
Model should looks very realistic, not some cartoon stylization or something.
Maximum triangles count for that model should be around 5 000 tris. Less tris = better.

Its a kind of easy work, but i need to find someone, who knows what is:

- clean topology (squares without smoothing errors)
- Unity 3D and preparation of usable textures for that engine
- Substance Painter with template for Unity 5
- ability to make textures very realistic with 2048x2048px (textures can be done from photos, but should be PBR

As a first outputs i need only jpg images of sword, where i can check the quality of your work.

As a final output i need every file you will make, that means, you should send me:

- 3D model as a FBX or *.max format
- substance painter scene
- psd file, if you make some changes in photoshop
- PBR textures (of course :) )

Here is a link where you can download a photos of ancient sword.
