Chemistry Question Writing for High Schoolers

Hello,

I am looking for an experienced high school/college chemistry teacher/tutor to compose multiple choice questions for chemistry. I will require ~200 high quality questions specific to my country's syllabus. These questions will primarily be based around analytical chemistry, focusing on equilibrium and acid-base reactions. I will require questions which are both easy and difficult. Good English comprehension and writing skills is necessary for this project.

I will provide some resources for you to base your work off. I have many questions for my country's syllabus which you can use as a reference for the difficulty and scope of the questions, however they *must not* be plagiarised. All questions written must be original.

This task is not urgent, and so you may take your time with the questions. Quality is far more important than speed in this case.

If you are interested, please bid in the comments below. I am willing to spend a large amount on this project, ~$500 USD for ~200 questions, but highly dependent on the quality of the questions. I will provide all interested freelancers with my resources and ask for sample questions, and will only move forward with the freelancer who is able to provide the best questions.
