I will totally do this for you. I have done many designs for companies worldwide - big and small. See my profile page for only some examples or www.kennybuck.de. Design is my passion and I always work on the design until my customers are pleased. I speak fluent english, so I am sure our communication will be smoothly. I did not have any jobs/ratings on this webportal yet, please look at my profile and website to assure yourself of my quality.
Can you tell me beforehand what is your app about?
