I need my Air Macbook fixed

I am looking for someone to help me fix my Apple laptop. Recently, I have been experiencing an issue where there are green gridlines randomly appearing on the screen. Additionally, my laptop is beginning to run slow and is overheating. It's important to me that I can get this issue resolved as soon as possible, but I am flexible on the timeline. Ideally, I would love to find a freelancer that is experienced with Apple laptops and can provide the best solution for this issue.
