-Get in the Yellow Pages. Deadline for Calgary is NEXT WEEK. In Calgary, everything is yellow pages.
-start by April 1st, detailing season is fall & spring, not summer
-Check out OCdetail.com (jng's page) for tips.
-get wicked logos on your truck & trailer; good phone #, good website; put your logos on your work tent and your water recovery system and your little sister's trike and...
-in fact, buy an ambulance for your truck and you might not need a trailer; most ambulances have full electrical and some water softening systems in them already, and after 450000k tend to go out into the market (minus the lights)
-do free work for office managers, church pastors, car dealers, drug dealers, school principals, university profs (they drive nice cars), etc., etc.; don't expect to get paid much for the first couple of weeks--nothing for the first few days; build a contract/wholesale client base of about 30% of your work so that you'll always have it--these are the kind that will stay with you in the colder months when you are doing specialized work out of somebody's garage your rent
-one member of DC would get up in the morning and knock on doors until he/she made the money they wanted for the day--they never went hungry and built a customer base
-get a killer business card; mine is sharp, but not killer
-do a search; this has been discussed before
