Mr. Fonsini,
If you were thinking of flying with a light a/c perhaps you could see if there's a smaller more local airfield near or quick to reach from your home and perhaps there's a handy alternative at/close to Las Vegas too ? You'll save a fair amount of ground transport time in getting airborne with less hassle, parking, check-in etc. and from the selected destination airfield an easy ride (I hope) to your customer or office facility. They might be able to pick you up.
Another thing, is if you wish to go/ return early late as the day's business proceeds, you can readily choose a departure time to suit.
Lastly the Cessna 172, for example, is a good solid safe platform, reasonable speed & not too expensive to operate, so paying for using one shouldn't really be awful and after all what are 'planes really for if not to travel.
[Remember the man who flew a rented one solo to the North Pole and back - so it has bags of endurance too.
Good Luck - go and ask around !
