Fast but effective products?

[chilistrucker]

After your opinions please. I know that quick and easy may go against the grain of getting a really nice finish but it is sort of the nature of the beast in this instance. Starting a job Monday for the summer that I did last year. I'm a chauffeur for a large family and look after their fleet of 10 vehicles, this year though i'll be doing it on my own as well as lots and lots of other things that are part of the job. I've got a 2 week window before the family start arriving so have a chance to give every vehicle a proper wash, vacuum and hoover, the full monty if you like before they turn up.
Once they are here though i'll have at best a 2-3 hour window each morning to keep on top of the fleet, so what would the pros recommend for quick but effective finishes? I won't be doing 10 vehicles every day probably 2-3 on an average day.
Shampoo for wash? I don't normally use a jet wash, hose and mitt, then leather.
Polish for body, glass cleaner, tyre dressing, (although ok on this 1) bumper and trim finishes, alloy wheel cleaner, and interior trim products as well as leather products???
What would you recommend? TIA

Thanks for the replies
The nearest place to the house where I can have a nose for these products is Halfords near Staines, but happy to travel a bit further a field for the right products.
