I used a template by Daily Blog Tips that was converted over from a WordPress template through eblogger tips(I think).
Anyway, there are alot of free professional looking templates available for download for free on to Blogger. That's what I did.
For an example see my site: homedadnetwork.blogspot.com
This Blog/Site was built completely free by me and I don't know HTML or anything, I can only cut and past it.
I think there are lots of free options available to anyone who would like to build a professional looking blog or web site for free.
If you'd like to know more anyone may feel free to contact me on Hubpages or email me email@example.com etc.
