Hello! It is my first time posting in this sub. Mods, if this kind of post is not allowed, so sorry, I will remove it

I'm not sure where else to get an opinion on this.
I'm a university student doing part-time designing PowerPoints and writing SEO articles for my boss. He needs me to use InDesign to make changes to existing brochure designs, rearrange content on pages to change from letter to A4, and redesign some pages. He asked me to quote a price, but I'm not familiar with the rates for this kind of work.
Please let me know what price I should be asking for (e.g. hourly/by page) and the rate. Thank you!
