Move Site Title

Good day. My website it www.21stcenturymom.com On the homepage, I would like to have the site title and description to be left justified but alongside the header image centered halfway between the top and bottom of the header image. I hope this makes sense. So, rather than the site title/description being left justified above the header image (which is currently centered) I would like it to appear alongside the image which would also require that my header image be moved slightly right of centered.
