Develop a CRM Web and Mobile App

We have a CRM we intend to develop. However, it must be done in Angular and using ASP.NET ZERO Framework (ASP.NET Boilerplate framework) as the back end framework.(The mobile can be in Ionic-React) We have some existing modules already but are open for them to be re-written. We intend for the mapping and routing functions to be based on Openstreet maps. The main challenge is time. We intend the full app to be functional within 2 weeks. There is minimum documentation but there is extensive screenshots of expected functionalities.
