As an alternate suggestion go to zainobros.com buy the detailing supplies (far superior products than detail businesses use) and do it yourself. It is usually the only way to get it done to your satisfaction.
You can also hit autogeek.net and get little brushes and such to clean all the nooks and crannies.
This way you can put a couple hours on your interior/exterior getting it perfect and have everything to maintain at 15 minutes a week.
When I had classic show cars and would not let detailers touch them, I realized I am the only one who can get the results I want without hiring a true expert detailer at $500 or so. Most of the car washes around here hire cheap labor as opposed to skilled detailers.
Just my .02.
