Custom Plugin Development for Real Estate Property Mgmt - Including XML Feed from Client's Data

We have a client with an extensive property management portfolio that we are looking to develop a new site for.

We need a plugin that will have the ability to programmatically pull in their data feed from the client's existing Yardi Property Management System - data includes, beds, baths, sqft, etc. Yardi feed would be in XML format.

We found a plugin that does part of what we are looking for, and wanted to reach out to see if your team would be able to partner with us on custom developing a plugin that has the functionality of this plugin + (hopefully) the following:
