Ipad / Iphone instant camera attachments

I want someone to design and make an attachment for the iphone and Ipad (preferrably) which will allow instant camera films made. The example is [login to view URL] this is where once you take the photo you are able to release it into a film image. I would also like whether the design for the Ipad can be altered to print paperwork, (therefore working just like a printer) the paper would need to be altered so that would need to be small than A4 as the Ipad isn't that large, I would like to know how cheap this can be made. It must be small and feel like it is a small attachment on the iphone possibly as an Ipad cover so that it doesnt feel like it is making the entire thing bulky. ** I also need you to ensure that this is not breaking / infringing patents this will be your responsibility also I need you to file a patent for this once it is has been completed with obviously my ownership**
