Finish a payment gateway for joomla component

I have a payment gateway plugin for Vikevents joomla component that needs to be finished. Please read carefully before you bid. I have made a video explaining what needs to be done but i will sumarize here: - Fix the reference not being generated properly - Add Javascript Popup with payment data - Generate email with payment data - Implement the callback function You can see the explanation video here: [login to view URL] Please mind that i have a working plugin for another extensions that you can take example from (i will provide all the files) so it should be easy, fast and straightforward to make the job done. My terms and conditions to work with you: - I will not tolerate changes in the agreed price. It's well documented what needs to be done. - You will evaluate the time needed to get the job done. I expect you deliver within the time frame. - You will work on your server until the plugin is finished. I will provide a copy of a test website ready for you to install. (via akeeba's kickstart) - The milestones will be organised in this way: 15% upfront with the aproval; 70% after the plugin is finished and all tasks working properly on dev server; 15% after installation and testing on production website.
