Photo app to post to social networks

I am working on a project where we need to create a touch screen application where by someone can take a photo of themselves inside a clothing store changing room. They take the photo and can then share it to social networks so their family/freinds can see the picture and share it. (Basica photo booth stuff needed - like take photo button, custom branding on interface, clients logo on pictures,view picture, retake picture, count down, etc) Pease note the below: - We want the app to be pre logged into the social media accounts such as twitter, facebook, instagram. Then be able to automatically post the photo with a comment or hashtag on the relevant sites or pages.. - For Facebook it needs to be able to post on the clients business page (We once did a photobooth app 2 years ago and used the Facebook Graph API. It unfortunately didn't work as it didnt post onto the business page timeline. As there was a security issue and we only got it to work as posting as an attachment on the side of the page. However we got it to work perfectly on a personal facebook page. So, I need to know if you are able to do this and can do this? If not then we maybe need to look at an external website and a app inside the facebook page that allows users to view pix and share them. Users still need to be able to share, like and tag themselves in the pictures. - Please advise what other social netwoks you can build this app to autopost to - i.e clients instagram page? clients twitter page? etc? I need some assistance on above please. if you have a photo booth app mock up that auto posts to a business page please let me know so I can test it. Thanks! Looking forward to your bid and detailed response as to what you can help with.
