Just to put forth some ideas to get the juices flowing. Consider donating a print or two to a local charity auction, approach a local bank to display some of your photographs in a lobby or such, the same for a hospital or office building that have some empty walls and even an airport. You might contact a youth group and offer to teach an under served child darkroom procedures or other photography techniques. Galleries are in business to make money and can be very picky.
As far as finding new subjects you can try a different technique with previous images such as an alternate process. Look around your house for something with an interesting shape. Some years ago my wife was going to discard an old wok that had a great patina. I kept it and started using it for a background and photographed fruits, vegetables and common objects that fit inside it. I used my 4x5 and made pt/pd prints. Some were displayed in a show at a popular frame shop and well known Cuban American photographer (the late) Mario Algaze who I knew asked me to print a limited edition of four of his own favorite images (12 numbered, an artist proof and printer's proof of each). It was a years long project. I wasn't paid but received three sets and the printer's proofs. Each print now goes for $2500-4000 in galleries. (i have 12 numbered prints that was my payment) Anyone interested

I'm sure there will be more suggestions and you will be able to share your talents.
