1)Well, When I first started detailing (at this level) was one year ago, It was just supposed to be a weekend thing for extra money, I had 5 years dealership detailing experience, so I was just going to make some extra money, but the more I started learning about REAL detailing. the more I realized how many Hack job cheapo detailers are out there. So that's when I decided to separate myself from the hacks. I studied hours and hours on other detailing websites, watching what all the other "Detailing Hero's" used for tools, products, and techniques. then each and every detail I would take my profit and buy the best tools, and products I could get. and now one year later I went from 2001 Buick lesabre to a 2006 Lamborghini Gallardo. My biggest secret is paying my tithes! No matter what anyone says, God has taken me from basic cars to super cars in one year! I stay faithful, honest and present a professional image, and the rest is history!
2) My first full correction was a Black 2006 Nissan Maxima, It was Super Hammered! He was a buddy of mine and I was at his house and the car was under a street light! I told him I could make it better then new! Once I did he was hooked! and it still looks just as good to this day!
3) Posting on the local Forums. Try to put together nice quality write ups that show dramatic changes. any car enthusiast will appreciate quality car care. you wont be able to jump into high price details. you have to prove yourself kind of. Let's just say I started at $150 for Full Corrections that took 15 hours to complete. The more I did them, the more I realized they were worth more.
but I still had a job at my dads business. while I was on my 3rd big correction (the 89 BMW) the owners dad came by with his Black Z06 vette (the 2007 Z06 write up) and said "man, I need you to do my vette" and then once people see that people trust you with nice cars, then all the other nice cars come to you with trust.
4) Word of mouth, and Facebook. you gotta make people think your the coolest thing since sliced bread.
Hope this helps?
