1. If you've already got a job, see if you can change your hours. You might not have to hit the pavement if you can do your job in less hours, or if it can be split between two people. You might even want to bring someone in as a job-sharing partner.
2. Get a full-time job, and negotiate hours once you've got an offer. It might be easier than you think. Most people are going to negotiate salary. If you want to bargain for better hours instead of more money, your future employer might prefer that anyway.
3. There are online job searches that specifically help you look for flexible jobs--that could include part-time work and/or telecommuting. One of my favorites is flexjobs.com. You can search their lists of jobs several different ways.
4. Look for companies that actively recruit less-traditional employees. Peruse the company's website to look for hints--one great indicator is to check who's on their board or to look for staff photos. If they have a lot of women in upper management, there might be a reason for that--maybe they're more flexible. Look for other kinds of variety in their staffing as well--Do they hire students? Retired people? Do they encourage their staff to become involved in the community? These are all indicators that they care about staff as people rather than just as robots who can get the work done.
5. Search out companies that are proud of their work-life policies. Of course, anyone can say they have great work-life balance when they're recruiting, but check to see if they've won any awards for flexibility (such as the Sloan Award or Working Mother's 100 Best).
6. Be prepared to ask for what you want. Don't assume that if you're working full-time or applying for a full-time job, that those are the only options available. Management may have set your schedule the way it is because they never thought of doing it any other way.
7. Think outside the punch clock. If you can't find a job doing something you like, why not invent one? If you're creative, you can probably think of a way to turn your field of expertise into a job, whether that means contract work for a single employer or freelancing your talent to several companies or teaching lessons. If you can market yourself, you can probably find a way.
