You can quickly do it in about 25 minutes.
But here is my suggestion:
Since it seems you don't want to detail the entire car, I suggest the following areas to clay....
hood, side mirrors, front bumper, rear bumper.
That should take about 30-40 minutes to do thoroughly. More towards the 20-30 minutes if you quickly go over it.
And yes, I still use the dish soap theory prior to claying.
EDIT: It takes me about 1 hour of clay time on a car that is in tough shape (paint contamination). It takes me about 20 minutes to do the parts I said above on my SVT.
Took me over an hour the first time I used clay bar on those parts (first time using clay ever). You get used to it as you go.
Also - Changing my initial time estimate.
