Hi!
I have experience with PlayBook applications. Please see my PMB with an attached .gob file, which you can rename to .rar and extract the .avi of a demo PlayBook application I wrote for a contract I had with an organization. It shows my skills with making an app look good, and work with a database as well as make web calls. I feel more that suited to write your application for you.
Please choose me. We'll be in touch.
