Looking For Someone to Make Sidebars For My Typominima Theme

My blog is here: https://AngelaDiGiovanni.com/

There are no sidebars in this theme (Typominima by Blogsessive) – just three columns at the bottom of the pages. I want to keep the three columns below, but I also want sidebars on both sides.

Is there anyone on here for hire? Or can anyone point me to a simple widget that will create these sidebars. I tried the “Sidebar Generator” widget, but either I don’t know how to use it, or it doesn’t work, or I have to have existing sidebars to replace it with.

Thanks in advance,
Angela
