I went the alt-ac route. I can't speak specifically to opportunities for someone with a social science degree, since my PhD was in a humanities field. So just some general advice:
-Cast a wide net. Don't apply for jobs you're unqualified for, obviously, but keep an open mind about how your skill set could be a benefit in a wide range of positions. Brainstorm several possible types of jobs.
-Informational interviews: do them. If you know someone who works in a field you might be interested in, talk to them. If you know someone who knows someone, ask to be put in touch. Don't be afraid to ask--people are almost always willing to have a brief conversation with you. I found these immensely helpful for learning about what certain jobs actually were like, what skills were needed, and how to pitch cover letters and resumes. Even better if you can have someone in the field you're applying in read your application materials and give feedback.
-Be prepared to take an entry level job. You may not have to--you may get lucky and find a job for which your academic qualifications are a perfect match, with an institution that will value them. However, many institutions and companies outside of academia will not care whether you have a PhD. They will see you as someone with no actual experience (yet) in the specific line of work they are hiring for.
-Universities often like hiring alt-acs for staff positions, because we understand university culture. Check out the job listings at universities and colleges in your area.
-This can be a tough transition. I spent several months unemployed/underemployed and went through about 50 applications and 10 interviews before I landed a job. I hope the process is easier for you!
