Math Typing in LaTeX

I'm looking for a LaTeX expert to help me type mathematical explanations and solutions for secondary school exam papers (O-levels standard)

The job involves:
- Solving and typing answers to math questions in LaTeX format
- Ensuring the formatting is clean and professional

Ideal skills for this job include:
- Proficiency in LaTeX typesetting
- Understanding of secondary school level mathematics
- Attention to detail to ensure accuracy
- Ability to maintain formatting consistency
- Ability to follow guidance and instructions

I have uploaded a sample exam paper that I need the solutions for.

Please note:
- It will be a long term job once I find a suitable typist as I have a lot of exam papers I need to type
- There is no specific deadline and I am not in a rush to have the solutions typed
