Android app design

I’ve hired an Android developer and developing a video player app and apply design at parts of views. I want to hire an app designer that are familiar with Android. I want to every background/foreground’s color and font’s name, size and color on the views.
Also image files with x,y position and size on the app’s screen that are made in the Sketch app. (I’ll use them as XML image resource) Also I need night mode’s color and image files too. I use [login to view URL] in the [login to view URL] for night mode. I need colorPrimary and colorPrimaryDark and more, so that’s why I need a designer who is familiar with Android. I want to receive the Image source file with Sketch, get the design guide by Zeplin. (I’ll send them to the developer) Don’t use copy right images and I’ll have the all images copy right by made you. I don’t want to reuse my images and icons, I want you to make all images and icons for me. I’ll put the milestone when make a deal and only release the milestone after I get the image files with the Sketch file and color RGB code and test it on my phone.
