Greetings.
We design apps and games from time to time, in our bundles we almost always design app icon and feature graphic, sometimes promo imagery too.
In order to determine turnouts and pricing it would be best to contact us with more information such as the app/game info, styles (for example we already know that you'd like material icon with subtle shadow) and so on.
Pricing is to be negotiated, usual pricing $40 a piece, ie $40 for icon, feature graphic etc.
Our delivery comes in editable PSD files, plus rasters for web use, with icon we include sizes of 32x 64x 128x 256x 512x and 1024x rasters in PNG but may also delivery DHD original.
Interested? Feel free to brief us on your project. We'd like to show some examples, however the bidding system doesn't allow us to attach files, we can do so only upon contact.
Regards. HEMA-MAXIM Design Team.
