WordPress plugin to extend functionality of WordPress theme (record audio on page)

I need to extend an existing WordPress theme and add some new features into it. The Wordpress theme is a job bidding theme and URL is [login to view URL] The source files to Wordpress theme will be provided to you. For project owner 1) Change "Locations" to "Languages" 2) Add new section to input text strings and select languages and optionally upload an image for each string and rate string 3) Can specify saving audio and image files in local directory or a S3 bucket For project worker 1) Add ability to record audio in high quality format and save it for the job. I prefer a solution that can work on mobile browser as well as desktop browser. Lots of Flash solutions but wondering if there's HTML5 that can work in Chrome in both Android and IOS. If not, I can live with Flash solution. - example codes are: - [login to view URL] - [login to view URL] - [login to view URL] - [login to view URL] - [login to view URL] - [login to view URL] - [login to view URL] - [login to view URL] - [login to view URL] - [login to view URL] - [login to view URL] - [login to view URL] 2) A special mobile version of page that allows users to quickly record audio for each string quickly. I will provide a quick mockup. 3) Can also upload audio file instead of recording per each string You must know WordPress and how to write wordpress plugins. Also must be expert in PHP and know how to handle recording audio directly on webpage and saving it as MP3. $200 and must be delivered within 2 weeks.
