Speed Website Scipts Loading/Page. Work on PostBack/API

Hello Freelancers, We currently have a nice website but it loads slowly. We need someone to speed up the scripts loading times, website loading time. We also use postback/API technologies for tracking purposes. We'd need you to work on the scripts to make sure they work correctly. Another important thing is to make the postback work on a 3rd party domain. Please make sure you have SKYPE in order to communicate easily during the project. Contact us for more details and good luck with the project.
