I'm no expert, successful or anything...so ignore my advice and cold call galleries.
1) I was not taken by any of the photos...and I think most people would have minimal emotive response to viewing them. So get a book on composition and think about telling an emotive story...or at least documenting something pretty (sunset, flower) with prefect technical execution.
2) enter your now better photos in some Art shows, and go to the judging to hear the judges' remarks....if you win, get honorable mentions or sell...your on the right track.
3) the suggestion of cafe/restaurants is solid...after you have some stock from entering shows, put the unsold works in cafe, restaurant, library...where ever.
