In Chicago (and LasVegas, and in England, their home) Truefitt & Hill will do a full straight-razor shave for $50.00 (tips extra).
It's the full treatment: steam towels, oil, lather+towels, lather, shave, alum, balm / aftershave. It takes about an hour or so, depending on the barber.
T&H are barbers to the royal house for the last one hundred and fifty years or so. They have shops around the world (and websites! -

There are some U-Tube videos on shaving with straight razors too.
Have fun, but remember, the other name for a straight razor is "CutThroat razor" ... and there's a good reason for it.
I have four straights myself, and use 'em when I have time. If time is short, I use a double-edge; it's like.30 a blade versus over a dollar for the 3,4,5 bladed commercial razor blades.
Then you get into the soaps, balms, aftershaves, brushes, (don't forget the styptic & alum)
Good Luck
