[WTB] [EU-LT] Custom 8-key split design & handwire commission

I am looking to commission a custom-built, fully assembled split keyboard for an 8-key (total) static setup. Something similar to the example in the image bellow.
Layout: 4 keys per hand – Index, Middle, Ring, Thumb (No pinky keys).
Switches: TTC Gold Pink.
Keycaps: Deep concave profile (especially for the thumb to rest at an angle).
Firmware: Simple QMK/VIAL/HID. Just map the 8 keys to numeric inputs 1-8 (I will handle chording myself).
Structure: Must withstand repeated lateral pinching stress on the thumb mount.
Location: Lithuania. Looking for an EU-based builder to keep shipping and customs simple.
