Description

BEFORE YOU PROCEED WITH A PROPOSAL: this project will only pay £600 and not any more than that. Please review the software specification properly and then make your proposal or accept mine.ALSO: the deadline for this project is 31st July, so your speedy and reliable development will be appreciated. If you think you cannot hit the deadline date then please do not place a bid.
I need a bespoke plugin created for WordPress for a course directory. We are a college and our new college website is powered by wordpress. We dont want to use any LMS plugin for this feature so we have decided to outsource the plugin creation on PPH.Please read the software specification properly. you must be very skilled in PHP and WordPress and have created plugins in the past.The plugin must be standalone, which means, we can install, configure and everything should work as necessary without configuring any code manually.
In order to go forward, you must be able to provide draft design proposal on how some of the features will look on front end and admin end.
Please find the software spec and data structure attached. Top certs will be given priority.
thank you
