Interactive Arcgis/Hubspot Map additional functionality

Our developers have built an interactive estate sales map that draws data from hubspot and displays it on a archgis map. We need someone to assist in developing additional functionality where people can click on a property and choose from a few plot and plan options which listed in hubspot Hubdb. The cost of the stand must must then add to the price of the chosen plan and give the total cost plan and give a total cost. We also need a google gps location link on every popup. We also need assistance with adding an additional layer for second floors and linking them to hubspot data and then finally adding small parts of graphic layers on our maps for undeveloped land

PLEASE NOTE: Quote your final price no placeholder bids as we do not have time to negotiate. We have already done the bulk of the work so this is just extra addons
