An Android app: Images/photo keyboard

I'd like to develop an Android phone application which is similar to emoj keyboards with the following modifications: - custom images are used with custom "emoji categories" in the bottom of the keyboard (keyboard keys will be larger in size than regular text keyboard keys) - the shared message (text+images) can be shared via MMS, email, Facebook or Twitter; it's important that the message shared is actually an image made (as a high-resolution screen capture) so that it can be attached as a photo on Facebook/Twitter - there are in-app purchases which allow buying some more custom images - it should also be possible to create an "own category" of images to be placed on the keyboard (as photos taken or chosen from an album and then added to the "keyboard gallery") - Flurry would need to be implemented with a few custom events Please let me know your fixed quote and how much time you'd need to implement it. Thank you.
