I need help starting a Blog/Vintage Resource!

I have done a lot of things to get all my networks lined up, but I seem to be stuck starting "the Blog".

http://archiviavintage.blogspot.com/

Since I am not a large vintage seller I mostly intend to use this blog as a valuable resource for vintage sellers and collectors alike, using my knowledge of 28 years of collecting and researching vintage clothing and furs, one that I can edit and add to on my own at will (I hope I can do that). I think you'll like it.

I am not that knowledgeable with html, and I am wondering if there are any great online tools for customizing my own templates or creating a more custom look? I am not so much interested in set templates as I am in customizing.

If someone could point me in the right direction, I'd be most grateful! Here is a link to my empty blogger blog:
