I could easily train virtual assistants to handle these payments and have an app created for encrypting sensitive data for facilitating the transactions through financial service partners from my main line of business.

Better to look at data.

With ADU's being so new and in most cases it being done for an owner who has no intention of selling, there are few data points for appraisers to currently use when determining the value of a home with a detached new construction ADU.

The real work is locating these properties and I've learned the best way to do this is to work in towns/areas that have online GIS systems that map; topography, wetlands, soils, etc. and assessors data available for download either from local sources or listsource.com.  

I'd suggest checking local Airbnb/VRBO data or using AirDNA to see occupancy rates and average nightly rates in the area.
