Hi. First, I wish you well on your new journey!!
Second, to market your cards, pages, services, here are my thoughts for ya:
Get online and research/google: how to start your own craft business
Network like a madwoman. Keep in touch with everyone in your day timer, email and address book. Talk to people everywhere--at the grocery store, in your neighborhood, at your kids' school. While keeping in touch, mention your new endeavor. Mary Kay calls it warm chatter when you take time to talk about them...it works.
Get reference letters. In writing. Copy those bad boys and give 'em out!
Check out
www.etsy.com sell your stuff online--handmade only there!
Make your own business cards. Make them eye catching = interest = business.
Get published--add that to your new resume baby! With pictures.
Perhaps join the bloggers of the world! I love lurking and reading about people accross the world. There must be a kickback on selling stuff from your blog/web page.....read: not experienced here....but bloggers love to blog and if you e-mail them, it's free and I bet most would be helpful to you.
Don't give up on your dream. I admire you for starting!!!
Again, best wishes on your journey.
