I am an open source GIS developer with an experience of 8 years. I develop applications and algorithms using Digital Image Processing and Machine Learning and I've delivered state level GIS projects. What you are asking for can definitely be delivered in 4-5 days. I can develop ML algorithms for analytics. Further if required, I can also develop 2D-3D web applications with query tools for you for better access, visualization and reporting.
Looking forward to working with you! :)
