Bigcommerce Expert required

Hi, We have developed a bigcommerce site which we need to refine, clean up the checkout process, update the fonts and generally get it to the stage where it will be ready to launch. The project is just updating code to remove sections, update areas, ensure the site looks and works correctly so we can thoroughly test. I expect this project to be done with constant communication over the next 48 hours and pay by the hour as this isn't a project that can be quoted on. You do need to know your way around Bigcommerce very well as we have apps that need to be reviewed and cleaned up also. Don't apply if you haven't worked on bigcommerce before as we need this project done quite quickly but also correctly. Please provide links to other bigcommerce sites you have either build or had significant work on. Thanks
