Implement Cross Domain Iframe autosize (EasyXDM) for Wordpress

Important Note: Please do not reply generic pre-formatted bids on this project. Anyone who does that will be immediately denied this job. I want genuine responses to my requests below. I have a main site which I would like to load an iframe inside of which is on a seperate domain. The iframe/child site will contain ticketing pages for the parent pages event. The height changes within the iframe as they navigate it, so I need something implemented which allows for auto resize of the iframe area based on the content size of the child iframe. I have seen these two solutions but I do not have the time to work out how its implemented. [login to view URL] [login to view URL] The parent page I intend on loading the iframe inside of is "[login to view URL]" The child page to load inside the iframe is "[login to view URL]~%20literary%20events?interface=8" I will need to use many iframes across the site however assistance to get this one working and then I will do the rest from there assuming it is setup to work on any page after the implementation of the above solution. Or if a simple plugin can be created that would be ideal with an iframe field on each page. I have access to edit the code on the parent site but the child site is limited to Google Tag Manager for inserting any html code. If this does not work please let me know how we can achieve a similar result and I will investigate if it can be done on the child site. Please reply with your suggestion, time frame and price. Cheers Will
