Design patterns for mobile cases

Hi, Read description properly before bidding I need to get my cases designed similar to this [login to view URL] these patterns are copied..so you will need to make a little tweak so they dont look copied. nothing major difference. So the task will be you need to design 1 pattern in 24 models/mobile shapes. so 1 pattern will be of 24 shapes..i have attached the mobile brands which models will be included. there will be 24 models in total. I want you to quote for 100 pattern in 24 shape for each..there are many patterns..currently i have 335. I want experienced team at low budget as this is bulk requirement..i will need regular updates..will need designs in .png and ai format. Thanks
