Building a Template

So I decided to start moving over to my own domain and I've seen tons of free templates, but nothing I really like. Can't seem to get that perfect one to look the way I wanted it to so i decided to start building my own. I'll be frank with you. It is a pain in the ass and I'm about ready to tear my hair out. I'm still not all that familiar with CSS so this is going to be a long haul.
