Construction extimate application -- 2

I am looking for a talented programmer to create a construction estimation application. The application will be used in a wide range of construction projects, both residential and commercial, so it needs to be flexible enough to work in different scenarios. I'm looking for features such as project management tools and cost estimation tools to be included, while the application should also be available on multiple platforms, including both iOS and Android. I am looking for someone who has experience in building apps for the construction industry and can create a user friendly app to meet my needs.
