Hello Sir / Ma'am,

Also my System is live at some restaurant's, with attractive and responsive design and much powerful functionality. I have a guideline and application demo in document form, if you like we can communicate via e-mail or on cell.
Cost of my application is also less then you're demand it will be a nice deal, if not then kindly just have look on it then decide.
Thank you.
