Dear Employer, We are really interested in this project as it is exactly within our scope of expertise. Working with a team who has both inhouse DESIGNERS and PROGRAMMERS means that you can take advantage of both: Our designers could help revise the design even in coding process, which is a GREAT benefit for any ongoing project. Quick Facts about us ---- + Established in April 2006. + 30+ team including 12 full time Mobile apps developers with diversified experience and growing. + HTML5, PhoneGap, IOS apps, Android apps, Web design, and Website development. + All our project managers speaks and writes good English and can voice chat on Skype (if required). + We plan and build. We don't "copy-and-paste" which produces conflicting codes and bugs. + Our team is 100% inhouse. So you pay for the real service - not marketing fee. In short, if you need an experienced team who offers *real English* communication, beautiful design & optimized code, premium after-service, AND in time and within the budget, then we are the choice!!! We look forward to get an interview chance so that we can discuss further in order to start on this project. Please message us back through this website so that we can show you our previous similar works. +++++Note: Since we believe in long term relations and are very confident about what we do, on completion of the project we also GIVE A FREE 90 DAYS SUPPORT for all our apps made.++++ Regards, Pinnacle Solutions
