Mobile developer to write code for app demo.

We are seeking an Android mobile app developer to assist us with our demo app. Our preference is to create the app in Unity, however, we are open to suggestions. Before we create the demo app, Step 1 would be for a developer to write some specific code for us, so that we can see it functioning. The code relates to positioning tools, used to align 3D models over the top of real world locations. There are several apps using various methods of alignment and we have mentioned those apps below: 1. [login to view URL] 2. [login to view URL] 3. MobiLive (see: [login to view URL]) As mentioned above, these 3 apps use slightly different methods to align 3d models in the real world, and we need a developer to help us decide on which is best for our needs, then recreate/copy the functionality tools. We have attached 2 user guide manuals which explain the tools required. Please refer to the MobiLive user guide (see pages 16-18) found in the link below: https://docs.google.com/document/d/18_sqqkkNjD5DZn9a7mNiaYFAq1-Sfp6cyAr9N1WE1Pk/edit#heading=[login to view URL] We have attached the Gamma user manual too. See page 6 to see how they align their models. Once we are happy with how the code works, Step 2 would be to work with the developer to create the remaining parts of the app demo.
