Create an iPhone and Android application

I want to develop a iOS and Android application. Need it completed and delivered within 20-30days. This application is an easy, simple, intuitive, and FUN online employee scheduling application - simply create, post and manage employee work schedules and communicate, and request time off. 1.)Create staff schedules from anywhere. Deliver to everyone with a click. 2.)Your team checks their schedule from their phone, tablet or laptop. 3.)Time off requests and shift trade requests happen here. Really, no calls or paper. 4.) Everybody loves the Message Wall. Think \"Facebook for work\". 5.)It couldn\'t be easier to forecast labor costs. We tally up the dollars as you go. 6.) Fly Notes keeps managers in synch. Assign ToDos, set reminders. 7.) Store your restaurant\'s documents with us and share them with your staff. You won\'t lose them and you\'ll print less. 8.) The Job Post tool is so simple you\'ll laugh. Never lose another resume. 9.)Contact information and important details on all staff members are at your fingertips. 10.)Your daily crib sheet (showing who\'s working) and any reminders you\'ve scheduled arrive via email each day. 11.) Bird\'s eye daily view each location\'s scheduled sales and labor costs. Blast a message to all employees at all locations with a click. 12.) It works on all devices. 13.) Drag and drop employees
