Hello, I'm interested in your offer. I have over 10 years of experience in web and graphic design, and 6 years of experience in UI / UX design, so I will be glad to make a great design for you!
As you didn't specify the numbers of screens, I will estimate the exact time/cost when you will provide me some more information on this project.
To see my skills and and to lower the chance of wrong choice, we could start with a trial paid milestone, just 30 $ for the first 2-3 screens.
Also, please take a look through my profile's portofolio, to see some of my app designs.
Looking forward,
Dmitry
