Need help finding suitable theme

I found a theme (suits) I liked very much to start my website: http://www.drmitchellbloom.com

However, I need to get it going and am not familiar with the coding to make the desired changes to it. People have been kind enough to provide some code assistance but when applied there are other issues that result that still need fixing.

I like the dark header and font style and the light color of the body of the page.
I am comfortable with setting up pages/layouts but not familiar with coding which is needed to make changes to the header in order to show my business (need more separate lines for text and need to vary their size from one line to the next) and the theme cuts off part of the title when viewed on a small mobile platform (iPhone).

Can anyone recommend a theme (free or premium) that would present with a similar color and layout scheme as suits but allow me easier addition of more text lines in header and options to control header font while also being responsive enough to show well on a desktop as well as a small mobile platform?
Or does it make more sense to hire someone to do a bit of coding to make the necessary modifications until I learn more as I get into this world?
Thx in advance for any advice.
