Startup for the selection of accessories for photo-video-PDA

My main place of work is an online store. We sell all digital photo-video and accessory to it. For more than ten years of work, I realized that a huge amount of time when communicating with a potential buyer to spend money not on the story about the “greatness and merit” of the chosen model, but on the selection of all sorts of batteries, charges and cases! Here is such a site: ACCUM.me To simplify the life of our store managers, we decided to create a website where you can simply find the right accessories by typing the fotik model! But it seems to me that such a site will be useful in general to all people who have a camera, camcorder or PDA. It is clear that, well, there are a lot of different models of technology and instantly it will not be possible to “hammer” it into the base and not to make mistakes. Therefore, I am waiting for your amendments, suggestions and comments both on the site and generally because of the need for such a service as a class!
PS The site is still in test mode, because glitches and errors are possible, about which I will hear the same with gratitude.
