I use CL, and got a decent amount of customers from it. Not lowballers either. People that just dont know where to start to find help, start there. Just be polite and treat them just as another customer. I try to update every other day, most of the time, it ends up being 3-4 days. Update early in the morning works good for me as it will be at the top of the list when people are searching through, during work.
