I need WP plugin - counter button!

Hi, I'm looking for a WordPress expert to write a simple plugin for me, using this plugin I should simply : 1) create a button with label text before and after clicking. 2) get 2 shortcodes for each button I create, one will return the button that will count clicks and one will return the total clicks on that button. 3) Option to enable/disable showing counts next to the button label. 4) First click on the button will count, second click will uncount. More details to be discussed with the candidate freelancer. Please provide some of your previous work/portfolio with your bid. Full requirements and screenshots: [login to view URL] Thanks!
