Creating Custom customer contact lightbox

Hi.
I have just created a website that will be connecting Land owners or property owners and tenants. It will be dealing with houses for rent specifically. The property owner fills a form giving out the house details and contact info. See it here LightHouse homes. The information is submitted to a database then displayed to customers in form of a repeater:LightHouse homes. That has proved successful. Now i would like the moment the customer clicks on the “contact” button it opens a lightbox that displays the owner’s contacts as shown on the screenshot below.
This means that the Lightbox must be dynamic which is impossible… but i know that with code it can work. please help.

Note: you must log in to access the form
