I Need Your Help

As I'm sure you may have noticed I have been giving my blog a little TLC lately.Just as I try to DIY things in my home, I thought I would try to teach myself a little about my blog.So, needless to say , I have been DIYing my blog layout the whole way.Slowyllllly....but surely.
But folks...I NEED HELP!!!

Does anyone know how to get that cute little header up top there centered???I can not figure it out for the life of me...I have googled...binged...no luck.I have tryed inserting the code I find in my searches, but it never works.
I may just have to break down & find a blog design company to help me out.Any suggestions would be sooo much appreciated!
