I'm a private tutor but I run an online business as well. If you are looking for idol posters where you can find it at nowhere else, you've come to the right place. Visit this website: http://starmerchandises.blogspot.sg/ (previously http://aszyjshop.blogspot.com/)  to find the design of posters you want. The posters are designed by me hence cannot be found elsewhere. Also, if the poster of your idol is not there, send me the a photo of him/her and I'll make it into a poster!!

Updates: My blogshop now sells other idol merchandises as well :)
