Cinema 4d Modelling - Phone cases

I need 3 phone case models to be created from photos supplied and on existing model to be amended and and then all 4 models to be textured as described. The 3 case models to be created from scratch are for the Samsung Galaxy S, HTC desire and the slightly less detailed iPod touch (4th gen) These need to be created as close to real life as possible 1:1. I have a 3d models already existing for the samsung galaxy s and ipod touch which I will provide for you to model the case to fit. If you want you could provide a separate estimate to model the HTC Desire phone but this should be included separately (at this stage i only need the case and not the phone as well). The amended model is to edit the camera hole shape on an existing iphone 4 case. Two circles to one rounded rectangle. After modelling, all 4 need to be textured using the supplied jpeg fle that is wrapped around the case. The texture needs to be applied in the same way that a table cloth hangs over a table. Not stretched or warped to fit - corners pinched in. The attached jpeg shows the existing model that needs the camera hole amended and re-textured. The modelling needs to be done using cinema 4d (v11) and not just exported to a cinema 4d format from max. To deliver: 3 x 3d phone cases models to be made and textured 1 x 3d phone case model to be amended and textured
