Adding functionality to the site

We need to redesign the site. But due to the limited budget, which is 3-5 thousand per month, we can only pull systematic optimization of the site (that is, not all at once). Now we are looking for a programmer who could redo something on the site once a month under my guidance (move the menu, add a button, etc.).I will deal with the content and visual content, you will only be required to perform any simple tasks to bring the site into the divine form.

I would appreciate your response, thank you!
