I've submitted a icon, would you like me to do the APP DESIGN?

What I had in mind was to receive overall colours, icons, buttons and menus that I can use in the whole APP. So how an alert would look like, how a menu or button would look like 

Hi,

We saw your project and we think that we can create something great for you. You can view some of our designed app interfaces here : http://www.behance.net/oxygencreatives . But can you kindly increase the budget. 200 dollars are not reasonable for designing 8 different screens along with a few elements. I look forward to hearing from you.

Cheers,
Oxygen Creatives

$200 per screen is small price...
