Android icon set for all devices on two different projects

I have two android projects. They are ready but designs should be completed. For all devices and resolutions the icons should be prepared and there MUST NOT be any copyright problem. Two logos, about 20 buttons and icons are needed wıth required solutions. Background colors and color range should be found by you. For this we need to communicate continously. I do not know the resoultions required, thats why you should be experienced on this. I will send you apks and you will prepare the design. IMPORTANT: You need to show me some portfolio.
