Leather Bag Design

Hi,
I have a simple idea for a dufflebag, pretty simpel basics but verry specific.
I have very specific measurements for the bag, the design and the accessories.
It is supposed to be a leather bag, i will provide all the material needed.
I am looking for a person that can create it for me on a high quality level. I tried it myself, but the quality of my leather sawing is too bad.
So need somebody with good experience in leather bag fabrication to create one bag for me following specifications.

I would love to hear from you and receive an indication of the price as well.
Thanks!
