Free listing: Photographers with Typepad blogs
If you have a Typepad blog (or are planning to start one), TypePad.com has recently launched a new TypePad gift shop that lists small and independent businesses. They have a photography section as well, and currently there are only two listings, so this might be a good opportunity to get a high profile listing. They have a "Submit" button at the bottom of the page. You get two links in your listing, one to your TypePad blog and one to the place where you sell your photography art. As an example, the two photographer shop pages currently listed there: Caryn Drexl and Moonflowers Photography on Etsy.
TypePad offers plans starting at $9/mo, with the more versatile unlimited plan at $15/mo.
