Magento & Amasty Extension Repair

I need a developer who is a genuine expert in working with Magento. We have installed an extension from [login to view URL] (Single Step Checkout) and it is not configuring correctly. Furthermore, we are using RocketTheme template, so some tweaking may be necessary to get things properly positioned on the page. Our site is a LIVE site, but is currently unable to allow checkout on the front-end. I need someone who is highly skilled in Magento and is available immediately. I will not award this project to someone wanting to LEARN on this project.
