Php APP. Must Be Responsive + Small Windows COM port app

I need a PHP app developed. I also need a small Windows app that listens on a COM port that passed info to the PHP app. If you have another way of doing then that's fine too. Full spec in the attached. Please read it properly and then bid. We have gone into things in great detail. I give preference to a company and NOT an individual. I require updates daily/weekly on the project status. Feedback will be sent to you which you will need to action. The feedback document will need to be sent back to me with your comments. I will require you to work on my test server for the development of the web based app. Company's with good ratings and great feedback will be at the forefront of my list. I prefer native English speakers as I don have time to explain simple English terms to non-native speakers. No upfront payment will be made. Money will be released as milestones as completed. Final payment will be released once the project is complete and all bugs and issues have been fixed. ALL SOURCE CODE TO BE HANDED OVER TO ME ONCE THE PROJECT IS COMPLETED. We will require work after this is done. This app will be improved upon and new featured will be added. I require a few UX options to be sent to me FIRST before any coding begins. I will choose the one I like best and approve it. You will then begin coding. This is a non negotiable requirement. Thank you and good luck!
