Create MCQs for JEE mathematics

I am looking for an experienced freelancer to create a set of advanced multi-choice questions (MCQs) in JEE mathematics, where also detailed solutions would need to be provided for each. The difficulty of the MCQs will be classified as advanced, and the format of the questions should be multiple choice. The solutions should be structured and detailed, so they cover all aspects of the problem. The person hired should have a deep understanding of JEE mathematics and be able to provide quality services.
