Yep, they do seem to be everywhere... that white Hummer is regularly spotted (seems like almost every 2nd or 3rd day).
I knew of someone who started up a Limo business about 3yrs ago, think he's still going although it's not as big a money maker as he hoped. In reality, you'd probably make more in a taxi. Limo hire costs aren't all that expensive, and there are quite a few to choose from... would be easy to price yourself out the market by getting frustrated at the income I think.
You need a Unique Selling Point to stand out I think rather than just being another Limo... something your A-Team thing had. Just get a Fire Engine and take all the hen parties around (although, there's a couple of them already).
How about a paddy wagon?... You could cuff them and everything... and if they get too rowdy, a swift baton to the nugget should do the trick
