Dear, Sir!
Thanks for your great idea!
I'm an individual freelancer who has many experience on mobile development and love it.
As you can see on my profile, over the last 5 years, I have developed 10+ successful mobile applications so far and some of them was very successful.
Only my development career is not so wonderful, that is the worst manner, but my development career in my company and my own effort would prove that is is not all.
Once you want, I should show my all apps for you. As you can see, those designs are nice and result is so good.
Everybody tell me so.
Once you choose me, you should feel that yourself.
I can submit the app to appstore and have several mobile phones so that I can test all delivers by myself.
About payment, we should discuss further more when we discuss about your project, I think.
Kind Regards.
