CRM web application with mobile application

I am looking for a reliable freelancer to develop a powerful CRM web application and mobile application. The CRM web application must feature contact management, sales pipeline, and task management. On the mobile side, I require both iOS and Android compatibility with analytics as an additional requirement. I am looking for a freelancer who can prioritize both the stability of the project and the timely delivery of the application. I also expect the freelancer to provide quality and continuous support throughout the course of the project.
