We need a very simple Joomla extension. We have already developed complete contact form application, We want simple extension/plugin that will show the entire application in Iframe code.
You can download our WordPress plugin from the link to get the idea of extension and the type of integration we are looking for.

After developing extension we want to submit the extension on the Joomla repository. Payment will be done once the extension is live on Joomla extensions directory.
