My website is www.torahfamilyliving.com, where I have books and resources for Torah moms and homeschoolers. I also sell used books and will be offering proofreading services in the near future. To add to the ideas here, I find that openly sharing each other's businesses in blog posts, newsletters, etc can be very effective. We need to know who has a business, though. Perhaps a directory would be helpful. One that we could link to on our sites would be even better.
