Add new features to a Wordpress mobile popup plugin - Easy instructions!

I have a wordpress plugin (a mobile responsive popup) already developed and I want to add a few new features to it: -A button in the popup designer that adds in the popup social buttons: like/share/tweet for website/facebook fanpage (these will be options that the admin will select). (The buttons will be custom graphics with this size: 30x30 px ) Explanation for the admin: He clicks on the "add social" button - a new area appears and he selects which buttons to put in the pop up and what are the links for each button (the website or the facebook/twitter page link -this will be added manually by the admin). -A new high quality popup template with a graphic element that shows a smartphone screen. On top of the phone the admin can add text. This will be used to encourage the viewers to send a text message using a specific text to a specific number. Explanation: pretty easy to understand. -Option in the back end to set the pop up to not show on homepage. Explanation: pretty easy to understand. -Live Preview of the popup in the right side in the back end. Explanation: pretty easy to understand. Other details: 1) I work only with individuals. 2) I'm open to your ideas and suggestions. 3) I will need support. 4) The budget is $150 max. 5) I suggest you check out the plugin (it's attached). 6) If you didn't understand something ask me and I will answer. I also have a few other features and plugins that I might develop with you if this goes well. Include "ICAN" in your bid if you want to be considered!
