Magento - Series of front end amends, block creation and Janrain implementation

I have a series of amends to do on a Magento store that will be going live shortly. These mainly consist of front end changes, addition of some blocks and the implementation of Janrain (3rd party sign in). Janrain extension has been added and configured but needs to be set up with Magento. You must be an experienced Magento dev and ready to begin work immediately and finish within 24 hours. All work must function on major browsers and tablets. Will provide more info to contractors of interest.
