Find Me a Manufacture/Fabricator for a Screen Protector Prod

I have a product line that is coming online asap. We are at the stages now we need to start scoping out manufacturers. We need to see previous experience and example of screen protectors made for mobile devices. We are going to start with the iPhone 4 device and then eventually move to other model phones. We are mainly looking at the clear screen protectors with a printed image imbedded in the protector. We are also just looking at the "back" cover of the iPhone 4. We currently do not need a manufacture but for the back cover screen protection. These will need to be high quality and we will need testing examples before placing our full order to make sure they are up to our expectations and quality control. There will also need to be two types of screen protectors produced. 1. A version with a self adhesive side to it for adhering to the back of the iPhone 4. This will need to be the exact dimensions of the back of the iPhone 4 and not leave residue once removed from the device. 2. A version that is the same as above but without an adhesive side. Dimensions to this one will be slightly bigger but generally the same exact size. That is it.
