Hi, I have gone through your requirement. I have already done the same kind of service+ecommerce App for one of my client. If you want I can show you the demo. I am having more than 20 year of experience in web & Mobile development. Since I have all the predefined functions for the app/web module , i can finish the work within 20 days. It was developed in PHP and iOS/Android platform. Please let me know. Thanks
