Hi there,
I can do this Blogger job for you. I will add adds to the sidebar wrapper and they will be only visible on mobile devices, as you need.
You said, "in mobile theme feeds are currently not visible", you mean RSS feeds or what? please clear a bit more. Will also fix RSS feeds.
Available to start right now. Please feel free to discuss anything regarding this project before starting.
