3D Design for Tajine Prototype -- 2

I need an experienced 3D modeler to create an STL/STEP file for a two-part Tajine (a Moroccan dish) for silicone manufacturing. The design will be used for prototype testing, so it needs to be highly detailed and accurate. The shape of the Tajine is mostly circular and conical, and while I only have general measurements, I'm open to suggestions for optimal design and functionality.

Ideal skills for the job include:
- Proficiency in CAD software
- Experience with 3D modeling for prototypes
- Understanding of manufacturing processes
- Ability to work with general measurements
- Creativity and problem-solving skills to optimize design


In case where you would like to work from the file I got, here are the modification to do :

Upper Part:
- Add an extension as in the attached image (See the extension in red)
- Reduce the thickness by 2
- Add my logo embossed as in the attached photo but bigger

Lower Part:
- Reduce the thickness by 2 (see attached file with black arrows)
- Create a recess of similar size to the extension of the upper part at the level of the red line
- Add my logo debossed as in the attached image (fill the space)


I joined a sketch with in red the modification need

I will also need a 3D render picture and video


Thanks in advance
