Hello,
My Name is Erez, I'm a project manager of an Android development team. I have my own android app: MySoccer 24/7 and I offer Android development services only.
My proposal is for what you wrote, if you have any Product Development Document it may help, if you don't I can write it for you and it will be useful in the future for iPhone development etc.
As the manager of the project I will make sure the development stand in time table and you will be updated during the work, includes getting part of the application on milestones.
if you have any questions, feel free to contact me.
Thanks, Erez
