Machine learning for brain mri segmentation using ensemble model

My company is looking for a freelancer to complete a Machine Learning project. We are looking to use an ensemble model for Brain MRI Segmentation, in order to create accurate tumor detection, precise boundary delineation and the identification of different brain regions. The successful freelancer should have experience in machine learning for brain MRI segmentation, and submit a detailed project proposal in their application. Our budget for this project is less than $500.
