Looking for a 3D designer for a PCB enclosure

I'm looking to have a PCB enclosure design for 3D printing in PLA. I have the original concept sketch for what I want it to look like. I recently worked with another low-cost designer who got close to what I was looking for but the PCB dimensions didn't allow the PCB to fit in the enclosure, the USB/power switch didn't align with the openings of the enclosure and he didn't include a section for the battery to be enclosed in the case either. I also would like something that looks a little sharper and less bulbous that what was made. I attached obj file for the PCB (dimensions are in inches even though it doesn't specify), the files for the concept sketch and then the files for front/back of the stl file that I was sent.
