Change location where the Call Now Button plugin appears

My site is avelim.co.il. The site is on Hebrew wordpress 3.5.1, using the theme Weaver II Pro 1.3.4.2 I am using the Call Now Button plugin [login to view URL] This plugin places a Call Now button to the bottom right corner of the screen which is only visible for mobile visitors. The text, display and functionality of the plugin were customized by programmers in the past to my request. Attached it the amended plugin I am using. I want one thing changed - the button should be placed on the top right left of the screen and not on the bottom right. The text currently displayed and all the other functionality of the plugin should stay the same. Freelancer shall send an amended version of the file for me to install. Plugin will be installed on a test site, and when successful on a live site. Work should be done in 24 hours after being awarded the project. Freelancer should allow 7 days for testing after he finishes his work, before getting paid
