Modification / Programming Upgrade of Wordpress Website

Hi guys, I have a website now that requires some help to upgrade it's function. Have a website here :- [login to view URL] It has audio tracks that is in a media playing section, that streams audio from the media library. Am using this plugin for this function :- [login to view URL] I need to upgrade / modify / develop an alternative to this plugin so that it can perform features as attached. Appointed vendor will need to ensure that all this will work perfectly with the current website database and not cause any conflict with this responsive website. Attached here are the requirements. I need this to be done by end Tuesday or Wednesday morning. (Non negotiable) Budget : $130 SGD Please send me your portfolio and let me know how comfortable you are with Wordpress backend programming and customisation. Thanks.
