Tried searching for "shoe shine" and "shoe shine" but didn't get any hits.

I have a pair of black boots that have scuffed toes. I need to get them shined for an upcoming trip but don't think I'll have time before flying. I'm connecting in DFW on Friday. My second flight is AE so I'll likely be flying out of B or lower D. (today's flight went out of lower D. My first flight could come into D, A or C based on experience). I think I've seen shoe shine places at DFW before.

Around 10 in the morning will they be operating? What's the cost? Where are they located and is there a particular shine person you can recommend in one of the terminals? Is one better at his/her job than others? How much time should I allow to ensure I have time to make my connection? My preference would be to get the boots shined near where my second flight's gate but open to suggestions.

Thanks in advance.
