Hello,
Allow me jump right into the point, since you had drawn a doodles/wireframing of your app, if possible you could send me one copy of your desire screen for me to create a graphic mockup for you. I'm sure this is more efficient than having me promoting myself here, from the mockup you'll be able to judge my skill and style of design. If it happen meet your expectation than only we further discuss the project, if not than let's just take this experience as making a new friend here.
If you have any quires about my previous experience do check out my portfolio and reviews left by the fellow employers. Do not hesitate to get in touch with me in case you got something to ask.
Hope you contemplate my suggestion
Best wishes
