beginner with SPUN theme

Hi everyone,

I am a beginner with WordPress. I’ve read many existing forums but I still haven’t found everything I need, yet, that’s why I am starting my own topic.

I am creating a website (stefanopagnoncelli.com) with the SPUN theme and I have some questions:

– how can I change the text color inside the circles? I don’t want it to be white but black (for exemple).
– how can I remove the “leave a comment” box in the article pages and insert a “contact me for a translation quoting” menu instead?
– is it possible to insert little flags on the right top corner of the home page and translate the whole content of my website into 1 or more languages? Do I need to install a plugin for that?
– finally, is it possible to remove or edit the bottom text in the home page “PROUDLY POWERED BY WORDPRESS | THEME: SPUN BY CAROLINE MOORE”?

I haven’t purchased the CUSTOM DESIGN yet. Maybe I need to buy it to do the modifications I need (maybe in the EDITOR sheet?)?

Thank you very much in advance for your help and sorry for the many questions.
