Adding "discount" and "event" feature in listing site

Dear bidders, We are looking to add some new features in out listing site. The site is Osclass based listing site. Below are the tasks. 1. Add event function to the listing. The user or the listing publisher should be able to add name of the event, select the business listing linked with that through drop-down menu, he should be able to put date and time in specified format. A checkbox will be required if its a weekly event. A textbox will be needed for putting details about the event. Once published event should be recorded in publisher listing "my events" along with "attendees" list. Attendees list will indicate the name, email and phone number if available and confirming date. One the display side it will show the event name, date and time along with number of attendees and a button to attend (in ajax). Only registered users can click that button. Once clicked it will register the user name in attendees list of [login to view URL] clicked "more" it will open a terms page in new window which will have general terms along with details published. 2. Similarly we will have "add discount" button at top. It will indicate name, discount %, business (default or choose from drop-down), validity, and details box. it should not display once it expires. display with option to claim coupon which will indicate unique random code and then show as [login to view URL] clicked "more" it will open a terms page will will have general terms along with details published. It will indicate the number of people claimed. On publishers side we will have list of "my discount" and list of "Claimant" where we will have the name, email and phone number if available and confirming date. 3. Put a feature called "upload ratelist". it will be a duplicate of existing "photos". it will be published in front in document viewer. Please let me know if you have any query or need more details. Please note that the site is mobile responsive and your code should not disturb the existing pattern, I am attaching approximate positioning of "discounts" and "events" and rate-list.
