	... | sed -ne 's/^.*site\([0-9]\).* /\1 /p'

will do the same. (The -n means don't print lines by default; and the
"p" means print this line if the sed matched)

You probably want to say 

	-printf "%l %f\n"

to get newlines in the output too. "-maxdepth 1" might be worth looking
into to, if you don't want to look through subdirectories.

find is a cool tool.
