Mathematics Expert Needed

Hi everyone, We need an expert in Mathematics who will work as a content creator for our website. Our website is a US-based educational platform. So, you must satisfy the standards of the US education system. The contents include the followings: 1. Video Tutorial and Lectures (He/She must have own computer, fast internet connection, HD camera with microphone). 2. Powerpoint slides on each chapter of a specified grade (from 3 to 12 and the slides must be formal and comprehensive). 3. Descriptive question paper with solutions (points will be specified). 4. Question paper containing MCQs with four options. (Each worth 1 point). 5. True/False test paper for theoretical questions (Mainly based on theorems, axioms and proofs and each worth 1 point). You may be required to also create/draw (electronically) pictures, graphs, tables or anything else related to these. We also need services like evaluating students' works and helping to overcome the difficulties they are facing with different topics. For that, you need to elaborate on some solutions or answering their questions etc. This time, we need 240 MCQs with four options (with no option like "all of them" or "none of the above") and 80 descriptive questions with solutions (each worth 5 points) and 80 true/false questions urgently. The topics that are included given below: 1. Set, Function & Relation. 2. Trigonometric function. 3. Permutation & Combination. 4. Binomial Theorem. 5. Probability. 6. Linear Programming. 7. Differentiation. 8. Integration. The distribution is like 30 MCQs, 10 Descriptive questions and 10 true/false questions for each topic. Please remember the questions must satisfy "GRADE 12 STANDARD". The contents must be "100% PLAGIARISM FREE". We are also expecting decent formal English writing.
