Custom Wordpress Plugin

I have a plugin now that posts out to 3-4 different social media locations. I need to add about another 7-9 locations. Also the plugin currently uses bit.ly...I'd like to include the option to use my direct URL (as it's pretty short anyways) or a URL shortner that is running from my domain...eg gocodes And one last functionality. Ability in the admin panel to tell it to select/submit to a) all, b) random, c) none or d) specifically called out locations via checkboxes. This last part can be a functionality added later. To start I want it to auto submit to each one available (unless that part is commented out).. Please only bid if you have done WP plugins before that post out to other sites.
