GetResponse 'New Opt-in Form' Code Integration

I have one Blog (Squarespace not Word Press) and 3x squeeze pages that require the 'latest' Get Response opt-in form code integrating. (Get Response changed this as of September 1st) I need the custom code installing and 'not' the javascript so I can track subscription conversions. I will also need exitsplash and google analytics code integrated into the three squeeze pages. The project is urgent as i've had to switch off traffic sources until the upgrade is complete.
