You won't find one.. but modifying either the free styles or the paid ones are not that hard.
Simple enough that even an tired old worn out beat cop could do it... I should know, I wuz one for 14.5 years.
I will try your suggestion on modifing a current style and definitely check out the link. I guess I have lots of reading to do. I know basic html and very minimal css. Hopefully it is not more than I can chew.
It appears this community is very helpful so I will definitely be around asking several questions.
