I really don't care for craigslist as a form of advertising your business. If other people are like me...I'd never seek detailing on craiglist. Mainly because they are obviously not established...cause if they were, they wouldn't need to rely on craigslist for work.
Not to say everyone on craigslist does lack luster work...but, I think most of us could agree that most of them do, and that's why they're seeking work.
Unfortunately, we live in a world where it's SO simple to seek out reviews, and feedback on businesses. I check reviews and feedback on everything now a days. Whether I'm traveling somewhere, seeking a service, product, etc. There's usually always some reviews out there.
I say if you want work...make sure customers are reviewing your work, and posting it. Preferably on google. Just having a couple reviews under your business will change the number of phone calls that come in.
Plus, craigslist is full of garbage, ha.
