"SOLVED" Logo & site name in header

Halo all. 
My name is Anton.
A friend of mine has chosen to use Squarespace as the platform for their website. I volunteered to create it. I have no idea what I am doing. I am going to be very needy, so I apologize and gratefully thank you all in advance for any assistance given.

I understand that it is easier for a site to be live to get better assistance, so although I don't believe it is ready, here is the website link;

Now & Zen Mobile Massage

https://www.nowandzen.net.au

My first issue is I would like to have the Site title "Now & Zen Mobile Massage" appear to the right of the logo in the header as there isn't an option in the settings.
I had tried some code in this forum, but I am either putting it in the wrong place (because I honestly don't know where it goes) or the code is not right for this particular website. For the time being, I have placed a logo with text there, which I don't really want.

Once again, any assistance with this would be gratefully appreciated.

I won't post too many issues in the same thread so as not to confuse anything.

Thanks again, regards.
- Anton.
 

P.S.

I take criticisms well, please feel free to give any feedback, good or bad 🙏
