custom made laptop bag in landscape format

I would like a laptop bag in landscape format for a 15.6" laptop, blue, in a style similar to Isabell Wambui leather, mixed with patterned fabric. It should have 2 handles with approx. 28 cm to carry it on the shoulder. In the front 1 small zipper pocket for keys and mobile phone, in the back a trolley belt. Inside 2 compartments (1 narrower padded one for a laptop and 1 large one e.g. for an A4 folder). 1 inner zipped pocket, if possible 2 more pockets for pen and business cards. The bag should be completely zippable, so that no small parts can fall out, e.g. in an airplane. Dimensions approx. 40 cm length, 30 cm height, 12 cm width. The bottom should have metal feet.
