Small Electronics enclosure

I am seeking a skilled freelancer to design and create a small electronics enclosure for my project. The enclosure should have the following specifications: Size Requirement: - The enclosure will be small, with dimensions max 100 x 60 x 10 mm - See pictures for first design draft Intended Use: - The enclosure will be for electronic sensors inside shipped goods. Can get cold and hot but not wet. - There will be a battery cover to easily change batteries - The design should include a low cost 4-wire connector that will allow the device to be electrically connected to a docking station. The docking station will be designed later, based on this design. - It should either be a cut-out for GPS antenna or a thicker enclosure to accommodate it. The antenna is 8 mm thick while rest of the box thickness is limited by battery thickness. A thinner and smaller enclosure is preferred, but designer should advise. Material Preference: - The enclosure should be made of plastic. - The enclosure should protect electronics inside well Skills and Experience: - Experience in designing and creating small electronics enclosures for PCBs and batteries. - Proficiency in working with plastic materials. - Knowledge of industry standards and best practices for enclosure design. - Attention to detail If you have the skills and expertise required for this project, please submit your proposal. CLARIFICATION (EDIT): The model casing will be 3D printed and should be sealed to protect agains humidity, while it to does not need to be submersible. The pictures show the actual electronics boards/sensors - there will not be a new PCB design for this iteration so the task includes securing these boards/sensors. The routing will be done with soldered wires and there needs to be space for this and sockets for batteries. Choosing a suitable external low cost connector is part of the task.
