Changes to wordpress booking plugin

A previous developer has made some changes to a wordpress plugin to customise it to our requirements. However they've let us down and were unable to fulfil the entire job. The plugin is a booking system that is 95% complete. The chosen developer will - Remove a link in the admin system - Restyling one page within the admin system of the plugin - Carry out changes to a form within the admin system - Adding functionality of a simple subscription system (Simply a name, duration and number of classes) Theyll be assigned to a member to ensure they can only book classes if they have classes remaning and their subscription has not expired. There is no online payment system. - Setting up sms, email and whatsapp notifications (the functionality is included in the plugin but has not been setup) - Front end changes (add calendar widget to front end website and link login/register button with the sign up page) The developer will be: - Specialised in PHP and wordpress - Available to start immediately - Delivering the project within 3 days. - Treat this project as their priority - Have a good understanding of the project - Do not bid on the project without being confident you can complete the project, and on time. If you have read the entire project description please include the line 'Shape4Life booking system' in your project bid, otherwise it will not be accepted. A full breakdown of changes will be sent to the chosen developer.
