And FoldingArt, you should definitely get in touch with your near art galleries and try to showcase your pieces in art shows. Art galleries frequently host exhibitions and this might be a great way to get the exposure you have been looking for. I also had my artifacts exhibited in these exhibitions a couple of times and also managed to sell a few of them. So this is something else that you can look into.
I can totally empathize with your situation because once you get the hang of this art, you just can't get enough of it. There is always something new and better to make and if you are good at it, I truly believe that you should display it for everyone to see. You can easily collaborate with local shops and sell your origami models there.
There is also the option of creating your own origami studio, however it's too early to discuss it. Check with the local shops in your neighborhood and see if you can get a good deal. You never know, that origami waste lying in your room could be a good source of income for you.
