JustCamIt modification for existing website

We are currently in the process of building this website: [login to view URL] This website uses software which is supplied from this website ([login to view URL]) which enables people to host their own webcams. We require 2 modifications to the website: 1) What we want to happen, is when the thumbnails on this page ([login to view URL]) are rolled over, it will play a live feed from the Hosts webcam for 10 seconds (if they are online of course). If they are not online, it will simply say 'OFFLINE' over the thumbnails. Here is a website which demonstrates how we want the live feed to work ([login to view URL]) (roll your mouse over the thumbnails to see). 2) We want the ability for Hosts to purchase the use of a 'double sized' thumbnail (which will be a double sized video preview when rolled-over). This will be charged at a set amount per hour. Looking at the script, I require someone who has good knowledge of javascript to complete these tasks. You can download the software which we use for the site free of charge here [login to view URL]
