Mcqs question bank

We would like to hire good teacher/teachers to prepare Multiple Choice Questions (MCQs) along with solutions for class 4 for CBSE Board. The MCQs will be in Mathematics. We need around 2000 questions (40 questions each on 54 subtopics) of varying difficulty levels (easy and hard). Some of the questions should be pictorial. MCQs must be genuine and not copied from different sources. Excel format in which this question bank needs to be created is provided. For the questions with pictures, the picture name should contain the question number it is associated to. All the pictures should be in one separate folder.
