My Car Needs Detail Cleaned, Any Referrals?

I'm selling my minivan (we're attempting to become a 1-car family to save money and less pollution) and I need to have it cleaned very well to prepare it to sell. Can anyone recommend a good place to take it? It will need a lot of work, like carpets cleaned, etc. Two small kids certainly take their toll on the cleanliness of a vehicle! LOL Have you had a good experience where they cleaned your car well at a reasonable price?
