Do some customization to the WordPress Job Board Plugin

You find it here: [login to view URL] 1. Be able to have job categories and subcategories. Ie Category is Teachers, sub cathegories are math, English etc etc. 2. Login with e-mail and/or username. You can find plugins for this on wordpress. 3. Integrate the payment system with WooCommerce plugin. I'm going to need to run additional WooCommere plugins for customization of the bills sent to the companies. I need payment options to be creditcard, paypal or bill. 4. Send customized e-mails to several addresses separated by commas when a user of a certain category registers. You can find code for this in the plugin Theme My Login. I want it to be exactly like that but instead of being based on which WordPress user you are it should be based on which job category you registered as. 5. Having verified icons with text fields in the user profiles which only the admin can change. Ie Verified licenses for medical personnel. 6. Choose for which job categories user approve should be activated for. 7. Adding end editing job alerts from inside the user dashboard and be able to choose to get an alert every hour if paid for. 8. Be able to use sub categories when searching for jobs. 9. Be able to use job category in the map search. I want changes to be made so I can still update the main plugin when the author updates it. Maybe add these changes to an other plugin? Please do NOT post automatic responses, READ carefully the description. Add the word "BUBBLE" in your offer so I know you have read this text. :)
