I read your project description, and i understand what you need. I have strong knowledge of Wordpress, experience with plug-ins development and customization, and over 10 years of additional experience with PHP&MySQL, HTML&CSS, and JavaScript. If you have additional information, or questions please send them by PM, thanks. PS: If you could send me more detailed project description and current plug-in URL, i'll reconsider lowering the price and time estimate up to one half.
