Hi,
Thanks for specifying the requirements clearly. I have been in app development in Sencha Touch with Phonegap/Corodova/Cueme wrapping for last 3 years. I have developed a number iPad/Android tablet apps and also a few iPhone/android phone apps in this time and have gained expertise in Sencha Touch, CSS3 , HTML5 etc. Even, for meeting special requirements I had to develop custom components like waterwheel component, flipper, vertical slider , tiles carousel etc and used those successfully in these apps. That is why I can confidently say that I can work on this app of yours. I completely agree with you regarding the steps you written that are to be followed. Please let me know if you are interested in working with me or if you want to see my previous work examples.

Thanks,
