Biomedical Journal Paper Code Help Python About Performance study of multiple CNN-based approaches against transformers-based approaches for brain image segmentation

I am seeking assistance with writing code from scratch to study the performance of a CNN-based approach for brain image segmentation in comparison to transformers-based approaches. I have specific datasets and i also need the freelancer to source additional datasets for this project. I am looking for a CNN-based as well as transformers-based approaches to be implemented specifically and compared among them and i need the freelancer to come up with new hybrid model including bith. The goal is to compare the CNN-based approach for brain segmentation against transformer-based approaches. I am open to any suggestions that will help make this project successful.
