When I was breaking into consulting, word of mouth was what got me in many doors (as well as starting small with projects). To this day, it is still my most effective mode of getting new work and projects.
A couple great sources I have used to land work and good publicity are
Craigslist, especially, has had the most effect on drawing in and also finding me projects. I post ads on there from time to time, and I search the “gigs” section a couple times a week to find relevant work. Sometimes even, I search locales outside my jurisdiction to post quick answers to those who may need assistance from afar.
