Hello -
I'm a freelance writer so I understand the challenge you're facing. Everyone in graphics and publishing has been feeling the pinch in this economy, so it's not an easy environment right now.
There are a lot of things you can do to drum up business, but they require consistent effort and they don't always produce instant results. I've joined a bunch of groups on Linked In and I'm getting great connections/leads there, so I'd recommend joining groups in any potential area that might have a use for your services - which frankly could be a very wide range, in graphics. Think out of the box for that one. If you've done lots for golf, could you reach out to existing country clubs? golf publications? equipment manufacturers? What about other sports? What about other fields entirely? Hot air balloons? Children's publishing? skateboarding or skiing or camping? churches in the area? sky's the limit there. There are probably many graphic designers groups on LInked In, but I'd join groups in other industries that would NOT have many designers as members, so you'll be able to offer your services when appropriate postings go up.
Meanwhile, begin a list of any and all potential contacts. Do up a postcard you can send - announce to everyone that you're back in business. Maybe offer a special to encourage new clients to try you out. Be active and find new people to contact on a daily or weekly basis, and just let people know you're looking to build up your client base. If you put the word out that way, very matter of factly, then I bet you will see clients begin to show up. Just expect that it will happen. Network with anyone and everyone you know. You can also look for postings on craigslist and such, although as you probably know, take all of those with a grain of salt and be careful of the many scams out there.
Finally, you need to have a stellar web site that shows your portfolio. I would suggest one in Flash, because it will look the best. (If you need help with a site, let me know.)
As far as pursuing your children's books, the most accessible thing is to self-publish. You could certainly contact publishers and try the traditional route of finding a 'real' publisher. In either case, I would suggest that you treat that as an extra or a hobby, probably not something you should expect to be a huge income producer.
If you have other questions I can help with, feel free to email me. Take care and good luck with everything!
